Almost every modern webhost will support PHP/MySQL, that is a fairly standard requirement. As far as free UBB boards, well you can't because UBB is not a free software package. There are other message boards available like phpBB that are free for download though.
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.
