Here's a list of The Game Programming Wiki's frequently asked questions:

Q: What is a wiki, anyway?
A: The short answer is that a wiki is a world-editable repository of knowledge, a community-maintained resource. Anyone can make changes to the wiki simply by clicking the "Edit" tab above a given page. For a more thorough description of the wiki concept, click here.

Q: How do I contribute?
A: See our help page for instructions on how to add pages to the wiki, and how to edit pre-existing pages.

Q: What guidelines are there for making changes to the wiki?
A: Please see the posting conventions page before making any changes.

Q: How do I upload files?
A: In order to be able to upload files you must first log in. Once you've logged in, you will see an "Upload File" link in the toolbox on the left-hand side of the screen. Be certain to read the upload policy before uploading your files! We do not accept executables of any kind, and we require that each compressed archive have an accompanying LICENSE.TXT file. Uploads that fail to comply with with upload policy will be deleted!

Think something else should be added to the FAQ? Reply to this post and let us know!

I'd never used a collaberative wiki before and spent quite a few minutes figuring out how to make a new page.

The answer I was looking for (I hope) was to type in the following IP
http://content.gpwiki.org/index.php/YourPageNameHere
And then editing and saving.

Good point, Balaam. Our help page has some links that may have shed some light:

I'll add a link to the this page to the FAQ!
