I don't want to revisit Clockwise's suggestion that posters are banned for their spelling mistakes, but I think in general all of us need to be a little more careful with our replies to posts.
There are more and more non-English speakers coming here, so to be fair to them I think we should stop using abbreviations and slang wherever possible. I have noticed a few posts that are essentially "I don't speak English too well, and I have no idea what you are talking about".
I'm not suggesting that we all take remedial English classes or use a grammar guide when writing - just try to avoid anything that will confuse anyone that didn't grow up speaking English.
Just an idea...
Once you've made something idiot proof, they go and invent a better idiot!
