Here are a few thoughts going through my head about rolling out the new site. It might be a good idea to give people a good advance notice that the old site will be locked on a pre-set day. Until then, have the basic new site ready to go, but have the forums disabled (except the hideout). This will give people the opportunity to register their username and get ready for the switch. Any name stealing could be addressed at this time. We also might want to make a temporary forum on the old site called something like “The New Org”. This would give us a single repository for questions and comments(they wouldn’t be spread out everywhere).
