Kate,
If you look after the name of a person who posted, i.e. Mark Cohen, you will find PM. Click on that and it will post a personal message to that person, like this one I am sending you, and will show up as a red notice at the top of the page saying that you have one message.

I will do this with this mail, and also post it to the thread about Mary Benson's stroke, since it looks like you didn't realize you were posting a personal message in a thread about Mary.
Blessings,
Barbara
