I'll help out with Behind-The-Scenes stuff I guess like story-making, costume choosing, etc.
You should add an "Appearance" section to each of the costumes that includes stuff like color of skin, length and color of hair, etc. (Example: Legolos would have long, blonde hair). I could also help out with some mini roles, like extras, if it's needed. It'll be better for taking screenshots.

Also, a big suggestion I had last time this was organized with Regulus: You should allow people to sign up as back-ups for roles in case someone doesn't show up. Even people that are already playing a character. That way those who aren't in the current scene as the first character role they signed up for can play as the character who doesn't have anyone.
Hehe, I already have backup role thing, and I have a section for Mini-Roles. *adds appearance and you to behind stuff*
