On-line spell checker

So I know you can use the spell check function whenever creating a post on blogger, but the same option isn't available when posting a comment. Usually, I just cut and paste to word, but I was working in the library on an internet only computer and couldn't use this....What was I to do? Well I used that highly evolved brain of mine and did an online search for spell checkers and came up with Spellcheck.net. No registration, no downloads, just cut and paste. It identifies misspelled words and gives you a drop down box to correct them, up to 5000 words. It's quick, its easy, no more excuses when your comments have gross misspellings!
