Yes.
-"You know those red squiggles under select words?"
--"Yea I get those all the time, the computer is always complimenting me on my large vocabulary!"
-"No, no it is not. It is telling you that you should check your spelling."
--"I'm not so sure about that, this is the internet no1 kares how U spull."
-"Yes.... yes that do, you have no excuse, just right click it, or google it."
Spellcheck is built into just about everything you can type in these days, I don't think there is any excuse. A small error here or there sure..... but remember to make use of the edit button.
My 92 cents.
