me didn'ts no thatz my werd spelin waz so inportant
Spelling and grammar are only important if you want to communicate clearly. And, I would assume that you would want people to read whatever you post, or why bother posting? But if it takes too long to translate what you've written, people will just skip over your posts.
If you really want to participate in written discussions, you might want to install spell check. It won't help with grammar, but at least it would have picked up on "didntz" "thatz" "werd" "spelin" "waz" and "inportant."
