We just purchased the newest upgrade for vBulletin and will more than likely begin the upgrading process sometime this week or early next week at the latest. I will try to post at least 24 hours in advance of when the upgrade starts, as there will be significant downtime and periods where the forums "don't look right/don't act right." We appreciate your patience in advance.
Don't panic! It isn't happening today, or even tomorrow. I just want to get everyone ready for it.
