Even though it's allowable... If I was in their shoes I wouldn't want to give out a source to some members just based on their backround(not ready, doesn't gave the knowledge base)... And if you were in there shoes would you random people PMing you constantly about a source(people get pretty desparate when they want something - this has nothing to do w/you just using examples)...
However long someone is here I feel coming outta the blue isn't very respectful... But who wouldn't want to get a great go to source(everyone

) but asking is very uncomfortable... IMO! But sure if one knows their stuff and has proven they can safely cycle then, I would agree that it would be nice to get some good feedback regarding sources.... Just my thoughts on the source stuff...
