What format should decimal numbers be in?
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".
Can I create new challenges for Valhalla?

How do I contact an administrator?
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]
What is Valhalla's stance on pen-testing?
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.
How long do I stay logged in?
Sessions timeout after one hour.
When not logged in, the "Online Guests" count will count your IP when you are active within 20 minutes.
What kinds of things does the Updates page show?
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.
How can I affiliate my site with Valhalla?
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.
How do I search for a specific user?
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.
