With the cost of IPS getting higher and higher every year (renewals, mods etc...) and IPS 4.0 not something I really care for, I have opened up another site using VBulletin and some of the great mods from DragonByte technologies. I was lucky enough to purchase VBulletin before their prices began to rise, and the mods from DragonByte I got at a substantially reduced price by being one of their testing personnel.
There are a lot of people that do not like VBulletin for one reason or another, but they do not charge a six month fee for their software and they do provide support for all of their software from VB 3 all they way through VB 5 (their latest software). Most of the mods that you use with IPS can be found at vbulletin.org and for the most part they are FREE. Don't get me wrong, there are some paid mods, and most of the skins are not the quality that you find with IPS but they work just fine.
So with all of this being said, I have opened up the Dog Pound Arcade utilizing VBulletin. If you have the chance stop by and let me know what you think about the new setup
