I'm no help either Glynis. Those there does look like there is a security feature. It looks like everyone has access at this point to my blog. I changed it to all No. However, I don't know how to add people to the groups so I don't know which groups you want to have access.
Hmmm, I thought it would be a good way to get my recipes out where y'all could find them, but I don't want to mess with something that's going to be too technical.
