This *might* happen as early as Tuesday, but it's almost certain to happen sometime in this coming week. When it does, we may experience as much as a day of downtime, or it could end up happening pretty quickly. There may be a period of overlap where both sites are active, resulting in a small but unpredictable period of lost posts. I'll do my best to forecast things, but since I'm not the one working directly with the server or the transition, that may be tricky.
Thanks for your patience, and pardon our dust.
