If you use a subscription model, you should make the value you are delivering very clear. A few ideas:
- Access to unique, valuable content and private forums
- Greater member privileges (e.g., storage, self-promotion ability, etc.)
Consider a free trial period or low-cost monthly billing to reduce the barrier to getting started - $50 isn't a large amount of money, but I would expect considerable resistance to signing up by potential new members.
One element to consider: if you find that search engines are driving much of your new traffic, making some or all of your forums viewable by paid members only will prevent your content from being spidered and indexed. You'll have to decide how to deal with this issue when the time comes.
