A successful forum is largely dependant on the members which make up the community. In the case of Video Editing Forums, I would classify the active membership as less than 10 members; This stands in stark contrast to the 1,000 registered members shown at the foot of the index page. In view of the volume of posts by these "hit and run" members, it is greatly satisfy to me that a select few indivuals spend a not insignificant amount of their time replying.
