First off, welcome to the family Nancy. It's a big one with several who have gone through exactly what you are facing. Unfortunately, I am not a diver (yet). Others will be along directly to answer your concerns.

Take a few minutes and read several other people's signature line at the bottom of their posts. We all use it to remind ourselves of the particulars each person has in their case before we respond on the forum. Everyone is different, so we need a way to keep things straight.

Then go make a signature line for yourself. At the top of this page, click on My Stuff (beside the green triangle), select Edit Profile, go down to Signature block and start typing. Hit Save and you're done.

Hang in there Nancy, your post is in one of the more advanced forum areas, one that doesn't get as much attention and traffic as others like Introduce Yourself, General, etc. If you don't get any answers here in the next couple of days, consider reposting your question in one of the two I just mentioned.

take care,
Tony
