Are there other ways to make revenue streams?
1) What other chess forum sites do you have a precedence for membership fees (this oughta help figure out the best route!).
2) Isn't continuing to subdivide the forum really just a way to continue to push the problem of organizing it better off into the future.
Something I think would be good if you go the route of making some kind of fee to participate in the forum would be a trial membership (3 months free to the forum and maybe one sample free dl of a subscription section). It would keep the in flow of new members to see if they find the value in their money before they contribute rather than being straight away turned off by the fee. The question I guess I have is if you went fee based does this mean the entire forum would not be seen by guests or that they just could not post (if the latter then the fee is silly).
Maybe an opening of the month thread should be started? Each month a different opening is selected. To participate in the thread there should be a smallish fee lets say $5 and the prize could be either a year's subscription for free or $100 or some kind of lesson etc. The best posts would be summarized in the next month's subscription update that would reveal the winner. It might bring in some additional revenue.
I have to imagine there is more ways like this idea to get nontraditional revenue streams than just 'subscribe or advertise!'
You could always try to get an additional tool section added to the forum such as 'recent games in tournament x,y,z, which usually ended up with their own thread anyhow. Only now, it would be an efficient tool that a person could purchase for a smallish sum (say .99cents). There all sorts of ways to innovate!
Somehow, the better threads end up longish and far too hard to follow if you weren't there when they began. Perhaps there should be some kind of system whereby a pgn is created of that thread and each person can be .50 cents for the convenience of getting the pgn over sifting through the thread endlessly.
