Mod Cooperative

My ideas are currently only very general, and I don't like one any more than another right now. As much as I'd like to do everything, I'm really only looking to start one of these. I'd like to go with something that might appeal to a wider audience, but at the same time, I don't want to do something the market's saturated with, so I'd like to have some feedback on these ideas.

Would you be interested in one (and if several, which would you most like)? Do you think something's too overdone (or done often, but still a good idea)? Have any ideas about plot/direction to throw in? Hit me with any thoughts you might have.

A Few General Notes:

• The RP will have an original plot and allow OCs only.
  
• It won't be PB. Pictures are cool with me, but they won't be required.
• Character journals will not be required, but if you want them, that's perfectly fine.
• I'd prefer to run it over LJ, but IJ's fine too, so let me know if you have an opinion there.
• I've been going over help and tutorial comms (this'll be my first big journal community endeavor, though I've run many elsewhere), but any tips you might have would still be appreciated.

You could also look at my general interest list here and see if anything pops out at you as interesting, because I'm totally open to other suggestions. Sorry for the TL;DR. > w>;;
