Forums Plugin - Multisite, is per blog activate OK?

Hi,
Forums install instructions say to network activate. Not all of my users will want to use the plugin. Which also takes up menu bar realestate. Will the plugin work properly if actived by each user and not network activate?

(In testing, only one forum can be created when user activated. If network activated a forums limit number can be stated and when deavtivated at network and reactivated at user, additional forums can be activated. Unforunately, the forums description does not show up.)
