I don't play well enough to give advice, but I have been helped with my game several times already. I have always sent back a personal message thanking the individual kind enough for taking the time to give me a hand. There is never an excuse for rudeness.
I've noticed a tendency for people to ask for various pieces of advice - perhaps on a number of subjects - but is it too much to ask to throw in an occasional "thank you" ?
What I'm saying is the more experienced players aren't an "Internet Resource" but ordinary folk. Yes they can show how clever they are and no one is immune from ego...but common on ....
