It can be a reference to a specific story, movie, or whatever, or just something vaguely SF/F/H-related. And it can be a lonely hearts ad, or selling something, or missed connection, or job ad, whatever sort of ad you'd get in the classifieds.
An (perhaps not that good) example would be:
Lonely alien seeks host for close cuddling, possible LTR. Send holo of face to Box 535.
I'll list the contributors after the ads, in the order the ads appear, so they won't go uncredited, and if you can indicate whether we have permission to post them on the website after the con, that would be great.
