I do have three other online forums listed at my blog http://pca-info.blogspot.com/. Click on the menu item called "Online Support Forums" on the left margin menu.
I will add more online forums and more information links as I find them. This forum (healingwell) is the most active and, in my opinion, has the most caring people. The HealthBoards forum is good, but it is very limited in what you can post. For example, they don't allow anyone to post links to other sites or offer their e-mail address to get in touch with other forum members. I do like HealthBoards for the information.
The google groups and yahoo groups are good as well, but sometimes there is some garbage you need to wade through to get to good information.
I have two or three more forums I'm working on to see if they are valuable and I am trying to register for them. I'll post more as I can.
All the best,
