Celia,
I received your email and looks like seven did all together not everyone.
Did you perhaps add the group to your contact list?
You should just start typing in Renaissance Writing Group and it comes up automatically because you have used it before. If you save it back as a personal contact you will start having trouble with it.
You can see the image below where I just start to type it in and it magically appears.
You might just send a test out to everyone.
