I just switched browsers from MS Explorer to Google Chrome. Chrome has a built-in spell checker and it has come in handy many times. I also like to read newspaper and magazine articles to get an idea of things like sentence structure and flow.

As for getting flagged, try posting in the Services section. I get flagged if I post in the Wanted section, but they leave me alone if I post in the Services section. That being said, I've had days where I've tried to sneak an ad in the "wrong" section and hope it stays up for an hour or two. I've had some luck that way. It's a hit-or-miss thing.
