I like Atlantis, and I like writing for the characters, but I also want my SG-1, you know? Unfortunately, it looks like a lot of SG-1 writers are dropping off or changing fandoms. I'd suggest either a flashfic-type com, or a prompting com (like suggesting a topic either every week or every other week and then compiling the results), but I would have no idea where to start and would most likely not be able to maintain it, even if I was able to get it off the ground.
