Sometime Sunday morning the site is going to switch to the new platform. Whenever I wander out of bed, I'll jump on the site and we'll all start exploring the fun together. The SBN tech team will be lurking here as well, so if you're having issues, throw up comments in the thread they post tomorrow morning and they'll address them as we go.
Given how well the transitions are going elsewhere, I'm not expecting any kind of problems. Mostly, it should just be fun to poke around the new playground.
