This is one organization you want to be a part of.
Not only do they have a team of technical experts who are experienced with wordpress, MU, buddypress and 100's of plugins, they answer your technical questions and help you get your site up and running --
It is the best money I have spent in a long time. Just access to their library of tested tried and true plugins is worth the little money this support membership costs -
If you are smart -- and you are a wordpress designer/developer -- you would go join right now --- and unfortunately I don't make any money on this -- LOL... but you need to belong, it will save you thousands of dollars in lost productivity time
