vBulletin 5 failed and for good reason. Why haven't IB moved onto developing vBulletin 6 yet? There's a chance they could redeem vBulletin. Offer it as a free upgrade for those who purchased vBulletin 5 out of good will, or possibly switch to paying for support every 6 months for access to the latest version instead like XenForo and IPB. It's a shame to see what was once the best forums software end up like this. They should move on from vBulletin 5. Its reputation is ruined and nothing can redeem it.
