For a while we posted Community Ads on other Stack Exchange sites to boost our traffic a bit. The original ones, from this post can no longer be used because the size has changed, and for the most part we don't have the files anyhow.
I was able to get versions of the previous ones from TildalWave and I modified two to create something that fits the new format.
Will this do? Does anyone feel like making up others?
In the interest of democratic process, I posted this here before unilaterally using it as an ad promoting us on other Stack Exchange sites. So, there is also the question of where to post it. I am thinking Science Fiction & Fantasy and Physics. I shall wait a day or two more before going ahead...
