Adding a new Entry
Go to the gallery, and click on the “Submit Your Game” button. Fill out the form, supply at least one link, and a URL to an image of size 705x344px, enter the captcha, and away you go! You’ll then be presented with a token, save the token!. It will allow you to modify your entry later.
YOu can also add a video by supplying a Youtube Embed Url, which should look like this: http://www.youtube.com/embed/videoid, e.g. http://www.youtube.com/embed/4s0lDD0x-7w
Modifying your entry
Go to your entry’s page, click the edit link. Modify you entry, and provide your token.
There’s also an API which you can figure out by inspecting the site’s source.
Every game in the gallery has its own comment thread. Use that feature to let the submitter know what you think!
