Last I heard, Community Ads were something graduated sites could do... but recently I stumbled upon this meta-PCG post, so here's a shamelessly stolen meta-post :)
It's simple: you make an ad, and post it as an answer here; then the community votes for what the next ad should be.
The highest voted ad once it has been at least two weeks, or there are at least 3 submissions with 3 votes each, or there is a submission with over 10 votes, will be posted on the community-ads post on various programming-related sites.
Here are the rules:
- Must be 220 x 250 pixels
- Must have a border
- Must be hosted through our standard image uploader (i.stack.imgur.com)
- Must be GIF or PNG
- No animated GIFs
- Absolute limit on file size of 150 KB
UPDATE!
The marked entry has been posted on the following sites - now all we need is some more votes (score threshold is 6) :)
UPDATE2!
These ads are now completing their run on the various sites. SO is now re-launching another cycle of Ads.
We cannot run two consecutive cycles on one site (against the rules), so there is no reason to be re-processing the community-ad contest.
