What Other Orchid Forums Are There and How Does OB Compare?

[My Green Pets]

I am aware of a couple other orchid forums like Slippertalk and rv-orchidworks, simply because they show up in internet search engine results.

I could be wrong, but I feel that the OB has an overwhelming percentage of transient lurkers or one-hit wonders, and a very small number of active members. It feels very much like an 'ask a question and leave' type place.

Are there other boards that have more loyal members, a stronger 'community' feel, perhaps? What other orchid forums do you frequent? What's the difference in ambiance you feel?
