When you say "levels" do you mean groups? If so then the only limit is the number of groups you can create in .threads. Each subscription group has 2 trial periods and then a regular billing period. The first trial period can be set as free as well.
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.
