I tend to be more of a "Why not" kind of person. I don't get annoyed easily. In fact, I probably won't get annoyed at a GM or player unless they are being an asshole, and even then as long as it's only at me, I'll probably let it slide for a few times until I put them down.  

I feel as if I throw out a line in enough places, a few of them will get a big bite and will become long running and fun. I agree with [@Pundii] though. Presentation is good. If I see an OOC with only a paragraph of info that looks sloppy, probably won't join it myself. 

I will say I only like moderate character sheets though. A good middle ground, with enough to where I have worked on them but not to an extreme. I dislike small ones, but I [i]really[/i] hate overly complicated sheets, even if I begrudgingly do them. I have an ideal for a character ready that I want to play, and I enjoy letting them evolve and learning their history [u]myself[/u] through the RP. I guess that's just the writer in me though. The best kind of characters are ones that write themselves, so over planning it is pretty much a death sentence to a lot of interesting characters. I feel like RP's with really complicated sheets are very tame when it comes to the IC with little actually happening because people are too concerned with the little things. (Not that you shouldn't be responsible and have info down of course). 

Whoever is GMing and the players are of course something I notice. But there's no one on the RP guild that I hate/loathe/have a problem with. If I see someone I recognize, then it's either a "oh, it's them" or a "SWEET MY MAIN MAN IS HERE. FUCK YEAH." 

I think what I mainly look for is if it is an interesting concept. Dragon Age or Star Wars or some other post apocalyptic nerdy shit? I'm probably in. I also am 70% Advanced, 25% Casual, and 5% free. I'll hardly join a Free Roleplay unless it's just a fun little thing like the Tavern. I enjoy Nation RP's, because I am a huge fan of strategy games and I love me some military history (or just history). I am also a big fan of combat, but I haven't tried the Arena yet. Guess I am thinking that I put that kinda stuff on a pedestal and if I join I might be really let down. Oh well.
