After a mere nine years of using WWWThreads, we've finally decided to leap into the future and start using MyBB for our discussion forum instead!
There are a variety of reasons why we decided to use MyBB instead of other alternatives such as phpBB, SMF, bbPress, or commercial offerings like vBulletin and IPB... but suffice it to say that, of the open-source solutions available, MyBB was the easiest for us to convert our over 120,000 posts into, as well as one of the best-performing with this size of database. So far we've been extremely happy with it.
All existing posts should be converted, and, as long as you've made at least one post on the board in the past, your existing username should continue to work. Otherwise, just set up a new user now and join in!
Let us know if you run into any issues with the forum conversion, or if you have any technical questions about how we've set it up.
