That read 729, 516 members...but the "new subscribers" list usually has the same names on it for days at a time, and are usually only a couple or so.
I see that there are maybe 30 free forums there. Other than Plant ID and Insect ID, The couple or so forums that I enjoyed will cost $20 to converse with folks there. I do greatly treasure them, but for the most part, they are all also on Cubits or ATP.
