Here's my suggestion: make a storyline/plot (or at least an outline of one) of your character(s) and send it either me or Lugia, where we'll invite each other and check it.
Really just to guide people into what they should be doing, as well as to wedge characters into the main storyline (or more likely have them run alongside it). They can be denied for any reason though; lack of realism, cliches, already done by others, continuity errors, etc.
Please note I have not consulted this with Lugia, so don't start sending them yet. Plus, this may be too complex to actually do.
