I have spent the last couple of days procrastinating building a Google calendar and LJ community to keep track of the big bangs across all the fandoms. It's still a work in progress, but it's there, with a summar of the next couple of weeks in Big Bangdom.

The community is at bigbangtracker, for your delection.

And for the record, I think I've signed up to half a dozen of them. *Facepalm*
