Some communities are not monitored and administrated and that's ok. Mine is though, and I will advise someone if they have not followed rules. Most are ok about it. I feel absolutely no remorse in addressing those who rant at me though, and often I make a point of making my point rather firmly.
I'm glad you feel you're on track. It's a really simple formula. Post well, outbound commenting and follow the accepted rules. It's not too difficult.
