I didn't think Janeway's Forum would last long. It was a modest try.
I think this forum has stayed active due to the single handed efforts of Omegaman. I tune in because he'll sometimes find a science story I had not found myself. And I read every thread he starts.
The most active here have always been the same. Kevin, Horatio, Martok.
Akula drops in from long stretches,
LCARS24 still puts his data up on the board from his projects.
As well as the Degee Guy with the amazing shots of the TOS Enterprise.
I'm usually busy but I tune in every day.
