Decimal numbers in your answers should separate the whole number and the fractional portion with a "." sign. So one and a half should be written as "1.5".

Yes, and it's encouraged. If you have an idea, just create it and submit it to an admin via IRC or email. If you have an idea for a new challenge category that is encouraged as well. You will receive credit in the form of a Hall of Fame entry for any challenges that are accepted.

You can submit content by creating an account, logging in, and going to the submit content page. From there you can also submit bugs you find on the site and suggestions you have for improving Valhalla.

For news, try to make your articles as unbiased as possible and avoid use of the first person point-of-view. Avoid copy/pasting articles word-for-word. Try to put it into your own words, and cite your sources.

For articles and code, make sure your content is original. Don't steal other people's work, and if you reference someone else's work give credit where it is due.

Vulnerabilities posted in the full disclosure are there to make public known vulnerabilities so that they must be patched by the site/application developer. The idea is to help eliminate 'security through obscurity'.

Valhalla is not liable for any attempt to hack software using vulnerabilities posted here, and Valhalla does not condone this type of activity.

The outbox size limit is 15 messages. If you send a new message when you have 15 already, the oldest one will be removed from your outbox. The inbox is unlimited.

While the Valhalla staff do not read your messages, our developers are able to see them in the database, so it's recommended that you don't post any personal information.

Valhalla is a place for sharing knowledge and ideas. Valhalla allows users to submit code, as well as science, technology, and engineering-oriented news and articles, and we also affiliate with other IT-related sites. We provide a biography and tags for each affiliate so users can easily find the content they are interested in. Valhalla also has an assortment of fun challenges intended to help users learn more about programming concepts, computer science, engineering, mathematics, and more.

If you have found a bug in the site or have a suggestion for improvement, you can use the submit function. Otherwise, if you need to contact an admin, the easiest way is to join the IRC channel. Information about IRC can be found here. Even if it says that no one is active, an admin is nearly always present and you can leave a message in PM with him or her. If you prefer to use email you can contact an administrator at [email protected].

We at Valhalla like to support those who wish to help us improve our site in any way, and so pen-testing is encouraged as long as it does not interfere with the normal activities of members or put unnecessary strain on the server. We ask that you report all findings to an administrator as soon as possible, and your contribution will be rewarded with recognition (in the form of a Hall of Fame post) and possibly a free t-shirt if we feel you have done us a service worthy of special thanks.

Sessions timeout after one hour.
When not logged in, the "Online Guests" count will count your IP when you are active within 20 minutes.

The updates page gives three different filters: 'Show Only Content Updates', which shows when a new affiliate or code/article/news story is put on Valhalla; 'Show Only Site Updates', which shows updates created by admins about site functionality; and 'Show All Updates' which shows all the previously mentioned things as well as new user registrations and comments on codes/news/articles.

Contact an administrator (see 'How do I contact an administrator?') and provide him or her with information about your site (title, url, description, tags, and detailed bio) and we will review your site and determine whether or not to add it to the list of affiliates. In return, we ask that you add us to your affiliate list if you have one, or make a news post on your main page about Valhalla.

On the members page, you can click on the alphabet letters at the bottom to narrow the search, and you can also enter all or part of a username in the URL bar after the "name=" part. You can use * as a wildcard, and note that the search string automatically assumes a wildcard at the end. The pound sign (#) by itself represents all non-alphabetic characters, but if you include other characters along with it then it will be treated as just a normal # sign.

Rules:

• Do not post challenge answers on the message board.
• Be nice and courteous. No flaming.
• Don't spam with excessive posts or attempts to hack the message board.
• Linking to an interesting site (or your own) is okay, but excessive advertising is frowned upon.

Other Important Information

• Any messages you submit within 10 seconds of a previous submission will be ignored.
• If you are viewing the first page, it will automatically refresh the messages periodically. This feature requires Javascript and AJAX support.
• Messages should be 250 characters or less; anything longer will be truncated.

Note: points are actually meaningless and are just there for fun. They do not indicate the skill-level of a member, only how active they are in solving challenges.

Reputation points are a way of giving recognition to users for their contributions to the site and the community. A user's reputation point total is calculated based on your submissions, votes on content you've submitted, hall of fame entries, and other points awarded. The formula looks like this:
    (10 points * number of articles/codes/news submitted) +
    HoF points +
    (1 point * number of upvotes) +
    (-1 point * number of downvotes) +
    Other points given by admins for special contributions (such as good forum posts).
