Any chance we'll lose the whole MB in this database prune or whatever you're doing?
There's always a chance, but we don't plan on it.
Is this part of a hosting move or just a pruning?
This is part of both a hosting move and a pruning. We'll backup the forums from this host/server, upload them onto the new host/server and then do the prune.
Any set time on the pruning, database switch, and whatnot?
Not yet.
Will we have to re-register?
Currently, the plan is to not prune the memberlist. So if we keep going to the plan we're currently going to, no, you will not have to re-register.
