I totally agree about this and I was noticing again the other day.
You have come a long way already, and I remember when people were telling you not to pay any attention to the harassment about it.
I mentioned this before, but I don't know if anyone noticed.
I have a program called "IESpell" that when installed it integrates into Explorer.
It perfect for forums and such and also has the "Add to Dictionary" function for when you need to teach it a word like FABO.
You can download it from here,

Once installed, open explorer and click "Tools" on your command bar and you will see IESpell in the list for running a spell check right in the post you are typing.
It looks like this.
