Update
I've completed a ton of the ground work for the new forum software. I have users converted, a permissions system in place, some BBCode parsing, user login and guest viewing, dynamic routing for SEO-friendly URLs, and some other things.
Pages that do work, are nearly pixel-perfect copies of what you're used to. I think people will be pleasantly surprised.
Along with that, I have the new TLS certificate working, modern user password hashing, etc.
(Chrome and Google should be very happy.)
As for functionality I promised in the initial release... "new user registration, outgoing emails, user login, posts, PMs, and chat" a good bit of that is still left to do. Actually, almost all of it is left to do (user login is complete though). I decided to add user profile pages to the list and tackle it first since it seemed manageable and important. New user registration and outgoing e-mails might be next, we'll see...
I'm going to be in the forum chat letting folks beta test the new software tonight if anyone is interested, since there is something to show and I want to knock out any issues early.
