Yes, but not just yet. We are still working on the admin features for Fleep - managed teams, conversations and accounts. These will be just like the regular Fleep teams, conversations and accounts, only with admins/moderators in control. Stay tuned.
Until then, all teams are democratic - all team members can add and remove team members, as well as add and remove team conversations. Most teams have found that the self-organizing nature works well, lowering administrative overhead.
