I'd be interested in helping GM-ing this if you'd like. 

Also, I'd like to bring up something in relation to this. How are we going to fit into Gravity falls? Will we be taking control of preexisting characters, or be making our own to solve the mysteries of the town?

That would be a great help! Thank you for offering. :)

I originally thought that it'd be better to do a mix of existing characters and also our own, gives it a bit more flavor. I'm not that bothered if the existing get a lot of attention or not, seeing as I'd rather have everyone create there own mysteries, almost.
