As some of you know, the software we run this site on (vBulletin) has been in various stages of beta-testing for several months. We made the decision a while back to move to the new version, even though it was slightly buggy, because the improvements were so great versus the older version.
Today, the first actual production release will be available for the software.
Some time in the next 2-3 weeks, we will be upgrading to this new production version, and hopefully will fix a few of the remaining bugs we're experiencing. We will be doing some testing behind the scenes first.
When we do upgrade, we will temporarily lose all of our custom modifications, but we will work to minimize the impact on our members.
