Oh yay for necro posts, excuse the revival of an older discussion.
I have two licenses for premium forum solutions which I would quite like to upgrade, my lifetime license for vBulletin 4 which I'd like to upgrade to vB5 and I have a Xenforo license which is a lifetime license but it requires an upgrade premium to get the latest version. Both were purchased whilst I had money coming in for theme design work I used to do but since my disabilities got worse I cannot dedicate time to design work so I can't afford the upgrades, shame about the vB5 one, that new software looks awesome, Xenforo is fun but I don't like it as much as vBulletin so wouldn't lose any sleep over it really.
