Hi Alice, I do hope you understand that some of us (like me) just had a problem understanding what your messages were about. I honestly still don't understand. there seems to be a number of URL's listed under your signature. I guess I'm just afraid I might miss something important. Were you letting the list know about a good site for research? I really would like to know. You obviously put a lot of time in on this. Regards, Pat Culp [email protected]
