Best thing to happen to my message board-posting is Google Toolbar. It has a spell check for all text that you enter in web-boxes!! I LOVE it! 
To answer the question: Grammar and spelling are somewhat important to me. However, I will say that my spelling and grammar really tend to slack off when using IM or posting on message boards... and even then, I have my pet peeves (the your/you're mix up DRIVES ME INSANE). Despite my tendency to slack off a bit, I'd say my grammar is still quite good... but, that goes hand in hand with the fact that I do a lot of academic writing.
