ron,
relax!
first off you're not a burden to anyone. your trivia section was a joy to read and you are a major contributor to the forum.
(i mean after all....who the hell writes more than you!(lol))
but buddy, you have to realize, if a singer willingly asks to have his singing critiqued, then he or she has to willing to hear whatever is said.
it's a choice, a choice that you made.....no one forced you to do this. me personally? i'm not inclined to do this unless i've really got it seriously right. just keep workiing hard and try to have fun too.
