LightRoom 4 Fourm--Any Good?

Hi,

Next Tues (4 DEC)  there will be a LightRoom 4 forum in Sacramento, CA given bt Matt Kloskowski. I never heard of him and wondered if anyone has gone to any of his forums. It's an all day session for $99. I just ordered Lightroom 4 from Amazon for their $79.99 special and was wondering if it's worth it, or can you "self-teach" Lightroom. It looks like it's affiliated with B&H Video.

Thanks,

Bob Schoner
