Hello Guest. We are upgrading the server's XenForo versions. This has to be done in stages. 1.5.18 ---> 1.5.23 ---> 2.0.0 ---> 2.0.12 ---> 2.1.0. I will likely upgrade each one and leave it for a day or so to see if there's any kinks. When moving from 1.x to 2.x, our add-ons will cease to work. Much of the functionality of said add-ons is now native within XenForo 2.x, so I don't think we'll miss much if anything. IF we are, we can try out new 2.x XF add-ons.
