Hi, Jan - keep watching this space. Bill in Alabama e-mailed me, and he's working up a response. If the thread has no messages posted to it for 24 hours, it will disappear from the Forum Menu, but you can always bring it up by putting a word from the thread title like change, and setting the "date" to an appropriate length of time.
I'm glad you posted your request. Looks like we'll finally have an answer to a question I've been tracking for a long time.
