Well, it will probably happen before 2019, and you won't really notice much of a difference.
But I'll probably be switching servers.
Right now the PFA server is running on semi-obsolete equipment, which is part of the reason why it's slow loading huge threads at times.
I'm going to be moving it to a new system soon, which has more hard drive space and a LOT more RAM.
IP addresses should change, so you may have trouble accessing the site for a few days while this happens.
I will update this thread as it gets closer.
