Sorry about that~ A lot of RPs have maximum limits for players because of the way they're designed, basically necessitating it. However, others don't. You will usually be told somewhere on the OOC page if the RP is full. You just have to give it a good read. Usually there is an accepted characters/RPers section for it, or it will be stated right up top. One of the two.
Style is all in the eyes of the beholder. A bit of confidence helps when trying, though. Find a style you like writing that other people like reading for the best results. If you'd like to point out these "terms" I can help you understand.
After we're finished with these questions I'll move onto posting.
