Wow, nice necro.
But for any other users who are interested, yes there are many ways to earn without ads.
1) Your own products
2) Your expertise/knowledge/coaching
3) Premium content for subscribers
4) Donations
Of these 4 options, donations are probably the easiest to set-up, but if you don't have an intimate connection with the reader-base then it's not going to yield much. Best for forums where there are plenty of members.
Arranging for Premium Content subscription is good if you actually have good content. Usually those with useful content that can be considered an expertise in a niche field can earn you good money. You can for example sell an e-book that has all the content or only give access of premium pages to subscribers.
Offering your coaching and products at a price is one of the hardest to do, but has the most pay-off. It's essentially like opening a shop and letting the money come in, only that your shop has far lower rent. The catch of course, is to have the product/skills that are in demand in the first place!
