As a newbie and lurker myself (cough), I have to admit that I wondered about the validity of the sponsors because I saw a post or two asking for sources. That struck me as tooo strange.
As for jumping in and posting more, I don't feel like I know enough to contribute constructively. I'm here to learn, because the numbers of REALLY knowledgable and helpful members here are awesome! I still beleive what my dear old dad told me before he left this shitty world:
"Shut up and listen if you want to learn anything".
Hopefully I'll post more in the future. LOL, one day I'd like to post some pics of myself to get some hints on what I need to work on. I'm in the best shape of my life and still improving, but a long way from where I want to be.
But I promise to not post or pm asking for sources!!!
