nobody wants to jump through a million hoops just to get some action around here. don't screen comments, don't make people fill out forms, don't for the love of god do fancy formatted tables that break the layout. if you want a private thread, make it yourself and link to it.
2) no celeb
do not advertise for RPF lines, and do not advertise for specific PBs. suggestions/guidelines are fine, 'someone to play a justin against my selena' is not.
3) use your words
be clear and be honest about what you want (or don't want) to play: characters, genres, fandoms, plotlines, whatever. "a nice guy for her?" is not a useful post, nor is "looking for a few more lines", nor "i just want to write!!!1" people can't read your mind, so give them something to go on.
