As you have discovered at the time of this writing, we've made some pretty extensive changes to the forums. We've updated the software from phpBB2 to phpBB3. We have also applied a heavily customized style (based off the "prosilver" style that ships with phpBB3) as the default. As with any changes--particularly with anything I've touched--there's likely to be some bugs. Specifically, you should expect to see some weird display bugs in this style from time to time until we have things ironed out. As it stands, most icons and pretty much everything else have been updated to match the current style. Some icons, notably the ones that appear in the upper right such as print, font size change, and so forth, have not been updated and look a little out of place. That will change in the coming days, but we still have a great deal of work to do along with the implementation of some useful surprises.
Display bugs you should watch out for are mostly related to the stylesheet. Prosilver does things a little funky, so if you see anything that looks like white text on a light backgrounds, please report it here along with any relevant URLs. Attaching a screenshot might be helpful but certainly isn't required.
The forums now also support RSS+ATOM feeds (hi Killem!) for those of you who like to have access to your news like that. You can either subscribe individually to each forum or follow the feeds associated with this site. If your reader isn't picking them up, here they are:
Generic feed for the site
Feed for new topics only
Feed for active topics only
To make things a little easier, I'll be adding some icons to the top of the forum somewhere for you to use to quickly access each of these feeds
Also, if you absolutely cannot stand the new theme, don't worry! You can still revert it back to something similar to what you're used to. To do that, go to your user control panel (the link is at the top) and click on "Board Preferences" then change "My Board Style" from "prosilver-goons" to "subsilver2". Be aware that subsilver2 is slightly broken due to some mods I applied to the forum. I haven't had a chance to fix it, but I'll get around to it. "prosilver" is the default theme that ships with phpBB3, if you're the adventurous sort and would like to poke around with everything. Neither of the themes outside of "prosilver-goons" have been branded by us yet, but that's a work in progress. All themes should work reasonably well in most major browsers. I've tested IE8, Firefox, Opera and Chrome, but there's no reason they shouldn't work in everything else (except IE6). If you're using an unusual web browser, just keep in mind that some things might break.
As always, post any issues you're having here. phpBB3 is a pretty significant leap upward from what we were using, so if you're having trouble finding your way around, just give us a shout and we'll see what we can do! If you're familiar with commercial software like vBulletin, you'll probably find some features to be fairly similar.
Enjoy the changes.
