If we end up sponsoring any conferences (and it's looking increasingly likely that we could be doing this very soon), we'll need a logo that conference organizers can put into their materials on our behalf.
Specifications:
I don't know how large the image ought to be, but I guess it should be at a resolution that would look good anywhere in the one-inch to six-inch range.
The image probably should include our site's current icon. The header graphic is available as well.

The image must include the judaism.stackexchange.com URL.
