The only reason I would get Infopop's web hosting is to get UBB.x, Chime and Thrive. You can't get them any other way. But if you don't want those and instead want to use UBB.threads, you may find Infopop's prices to be a bit...lofty.
Donate to UBBDev today to help aid in Operational, Server and Script Maintenance, and Development costs.
Please also see our parent organization VNC Web Services if you're in the need of a new UBB.threads Install or Upgrade, Site/Server Migrations, or Security and Coding Services.
