I know that Area 51 has ads for promoting proposals, e.g.:
<a href="http://area51.stackexchange.com/proposals/45110/buddhism?referrer=wfrtzfRZknfyJ6AWfccLUw2"> <img src="http://area51.stackexchange.com/ads/proposal/45110.png" width="220" height="250" alt="Stack Exchange Q&A site proposal: Buddhism" /> </a>
but I don't see anywhere that they offer ads for the betas themselves. Should we create one, or is there a standard, accepted way for displaying such a link on your site? Or should we just use the Area 51 ad?
Edit: another tool that SE offers, maybe not terribly appropriate for self-effacing Buddhists, is flair, e.g.:
which can be placed on one's website or weblog.
