LOL Thanks for the tip redring as Alex has completely installed CS2 now for me and I am forced to use it! LOL I love text in patterns!
Also if for some reason when you are making a text circle the way sfcgijill says and it doesn't come out quite right Copy the half that is right, paste it twice, flip one side and connect the two layers ;) This isn't only good for text but also works if you want to make a ring out of a repeated pattern like circles or gems etc
