I've learned a valuable lesson. Never try to compose somthing in the thread message box. I find it hard to check spelling that way. You can check with your books as references, but not references in other ASCII files on your computer. I do not have too many of these, since it is true as the professor said that there are a lot of self-styled experts on the internet, so I'm pretty chosey about what I use from it, and never anything from anyone I haven't some good reason to believe is reliable.
