My suggestions:
1. Forget grammar check completely. One of the polls in this forum showed that two thirds of the forum people are no native english speakers. Go play grammar nazi in a university or high school forum
2. no arrogant attitude and disrespecting comments against people with a different opinion from the moderators. this lets you look stupid in front of the whole community. discussion on irc showed that most people agree with that.
3. Telling people when and for what reason their posts are deleted or censored
