M'kay, I'm not an officer or anything, but I did see some things I can answer =)
There are, indeed, characters within the Symphony who don't get along IC'ly. I can give you a good example-- Ter 'thelas hates everybody. Kidding! But, he is not on very good terms with any of the characters who were once part of Archeons 'evil quilting club,' especially Peredhel. Per was once Ter's best friend, and when he went evil and Ter wouldn't join in the fun... Per gouged his eye out.
But, there is a thread somewhere in the guild discussion where ppl have posted to tell who their characters are and how they relate to others. {Edit: To add a link!}
http://www.symphonyofeternity.com/forum/index.php?topic=1429.0Also, as weird as it may seem, any chance of a Forum section for 'profile' pages, of our IC selves, maybe some general idea of what might be generally known or easy to find out, vs background info that it's unlikely anyone outside certain circles would know.
There is a character bio section in the guild-only forums =)
Maybe some way of linking the people who want to be avid Rpers with one another, and the ones who are not interested in RP don't get bothered
The RP discussion forum is a good place to start!
