Communities plugin problem...

I installed the communities plugin earlier today and have been trying to play around with it... from the admin account I can see the different communities and can write, post, respond... on all of them. I then made a subscriber account to see if it was all working correctly... I can do a search and see the communities but I can not join any of them... when I click "join" it say's "you have joined "xyz" community but when I go to the communities tab it still says "You currently are not a member of a community." I created a community to see if I could join it on the admin user but I ran into the same problem... Also, as the subscriber user I can not see any of the pages, boards, wiki, or news... all the pages are blank... but as the admin user I see them all...

Does anyone have any thoughts?

Thanks!
