TACTIC Enterprise and Team are Both Open Source.

Just want to clear the air on the difference between our Tactic Team and Tactic Enterprise Versions.  Overall, there is no difference in terms of usage and both have been released under the EPL Open Source license. The only difference is that Team is a simple, self contained install and Enterprise needs to be installed on a server running a database and a webserver.  Team can be a great way to get started and use Tactic in smaller scale but if you want to use Tactic for many people than you will want to use the Enterprise edition.
