Babe, if you don't already have cred from all the crazy meta you do, plus the fact that you churn out copious amounts of quality fic -- oh wait, you just mentioned that as a facade because really you're just a freak who spends ungodly amounts of time in fandom.

I think you should do whatever you want (which is what i suspect you'll do anyway, and i suspect that it'll involve a multiplicity of ficathons over the summer) but i will say that it sometimes seems like everyone and her roommate tries her hand at running a ficathon, and i rarely remember the names of the people who run them, so it's no way to build fannish cred, but you have lots of neat fannish people who read you, so you're likely to actually get a substantial number of participants if you do do one, which makes me happy because in order for a ficathon to be good it needs a minimal critical mass of participants.

P.S. I heart your Subject line.

The singer is spelled Sarah McLachlan, though.
