For those of you into forum technology and the like, we're migrating away from OpenTopic, towards UBB.x. Those of you who have been with us for a long time likely recall that we once ran the forum on UBB. This new version is light-years away from those olden times (yes, ly is not a measure of distance, I know), and owing to a number of factors, it's more suitable to what Ars needs to grow even more. In any case, the dedicated database server plus the front-end web servers are ready to go, primed with 8GB of RAM and plenty of processing love. We'll have more info as the new forum gets ready to launch.
