Remember, anything you change in spell check, ONLY affects that computer.

We have to figure that we will always have a sub par spell check, but then again, few programs do. The large office suites, probably some others. I pay around $150 a year for medical dictionary in Stedman's which is awesome for Outlook and Word.
