Have been following this site since early in April and have really enjoyed it.
Decided to jump in so I can add my 2 cents when I feel like it.
I really have never been active in the various social sites (FB, Linkedin, etc. etc.) that are out there but this one seems to be worth the shot at it.
Glad I happened to come across UHH and the wealth of advice available.
