Naomi had a great suggestion on a post somewhere on my blog!
"Now I know almost nothing about clever computer things, but wouldnt it be
lovely if we could each design our own calling card, so we could leave them to
let each other know we have been, on those days when your brain is just too
sleepy to do a comment...? "
calling cards similar to those used in Victorian times! when we visit blogs and are just too tired to even think about a comment but really enjoy reading the blogs.
