I've been a devotee of Kuan Yin since the 1970s. I took vows to her as my goddess when I was in a Wiccan Trad, and I now worship her as a soiltary (I call myself a BuddheoPagan).
I run a group for Kuan Yin devotees at Eons. com. The group has a library of sutras, articles and other information about Kuan Yin, an image gallery, audio recordings of chants, videos -- probably the largest collection of material on Kuan Yin in one place on the web. If you would like to visit the group, it's athttp://www.eons.com/groups/group/the-chapel-of-kuan-yin
I've also written a blog about Kuan Yin, which describes my experience with her and gives a lot of information about her. You can find it here:http://www.paganspace.net/profiles/blogs/my-kuan-yin-blog-originally
