What really pisses me off??
1. People that dredge up old threads, and give advice on how to solve an issue that had been resolved years before.
2. People that ask a question that had already been answered, sometimes in the immediately proceeding posts.
3. People that start threads with no other apparent motive than to start a crap-fest and subsequent burning of popcorn.
3A. Starting such crap-fests on the main tech forum.
I feel much better now.
