Do I have to be invited?
I don't think you need to be invited. If you go there just click join group then the admin will add you when they see it. It's called The J-Pouch Group. It's a great place to chat because you get responses so much faster. There is about
1200 members there. I don't put my email address in public forums (learned that the hard way) otherwise I would be happy to chat with you. :)
