The House of TrekBBS is difficult. I think quite a few of us have characters on KDF side, but play them rarely.
So the House has very few toons who signed up.
What the house needs is members who are actually online.
Class and career don't matter one bit.
Perhaps trying to maintain two fleets with the number of members you have is not possible. Have you considered merging into an existing Klingon fleet?
My KDF fleet is pretty big, but activity has been way down since SWTOR came out. Merging into the KDF fleet could be a win-win situation. You would be joining an established organization and you would be providing them with fresh blood. Plus you'd still have the TrekBBS Klingons all in one place for running any missions or events.
