An interest check, 1x1 or group, should have the same goal: to convey necessary information to all interested parties. The information that is necessary differs a bit however. In a group RP, I want to know what kind of adventure we're going on so that I can make my character. with 1x1, I want to know if the topic creator and I are going to be a good fit. Sadly, that's a difficult thing to really advertise, so I end up looking for reasonable people who share some of my interests.

I don't have a very strong opinion about most of what's been said, But I would like to talk about [i]topic tiles[/i]. It's the first thing you see and determines if someone clicks on your thread. There's nothing wrong with naming your thread "TrumpetGirl5345's box of wonders" or "Desperato's adventure search" or even "M looking for F (18+)" But you look like the other 98% of interest checks when you do this. If you have a common theme with all of your plot ideas, put that in your title. I'd be more likely to click on "Adventures in the wild west," "Lookin' to start a rock band," or even "Lesbian Zombie Hooker Nightmare" than the see of generic titles.
