I went to look at and compare spell checkers. I separated the good ones form the ones that don't help but just waist our time. I concentrated on the prose and cons of each program.

"Spell Checkers."

Of course, most people don't go out and by them separately. They are included with other software. Mini times they are in with the free software. Some of the web browsers have them. Most word processors have them. Some people buy them for special purposes: for medical stuff or other highly technical things.

Some spell checkers are flexible. You can get some kinds that will install themselves right on Microsoft Word so that it appears on the toolbar. It can be very convenient, or it can be a pain if you've ever gotten one that you can't seem to get rid of. So, you have to know what the affect will be before you due something drastic. Spell checkers are really grate. They have taken the lode off of our mines and freed us up to think about more important things.
Give me your tired, your poor,
Your huddled masses yearning to breathe free
And I'll give you their energy
Divided by the speed of light squared
Yearning to breathe free.

One day, I am tolled, mankind will not have to use his and her powerful minds on dumb things like remembering how to spell stupid words. Our minds can be turned to better things and the planet will be better off.
