Just to touch on what Kejtar said...
We are currently running the last version of the 2.X.X vBulletin software. Version 3 has some very interesting features, including the linear layout, and a "modified" threaded layout. Will it look the same as the old software? no, but it will have a window that shows the threaded layout.
Version 3 is still in Private Beta. Once it seems stable, they will release it for public beta testing. Depending on the feedback of the private beta testers, a decision will be made to upgrade at that time.
That is only one of the improved features. Optimization and goodies will be nice. It also has some parts that will specifically benefit
as a club, but we will go there once we see how those parts work.
Keep in mind, many of us (including this writer) liked the old forums. We did not just wake up one morning and decide to change. There are good reasons for the change.
We appreciate the feedback, and stay tuned... more good features are coming.
