I am definitely interested. My actual posting schedule however is somewhat slow at around 1-2 large posts per week. Shorter brainstorming posts ought to come in faster however. If this is ok with you then we ought to get along just fine. :) 

I am also a fan of the superheroes/villains, Sci-fi, Fantasy and Mystery areas, and would love to build something long-term. Plotting is half the fun for me, even if the RP falls down.
