I then clicked on the NEXT 'comments' tab - under the next entry upon ROZ/RIMINGTON's blog to be told that my ID was 1311:

More than that - the website had apparently 'saved' my comment - yes but I hadn't left one upon that comments tab - had I? I had sent one from the previous comments tab.

Secondly, I am not able to use my BLOGGER ID as blackrabbit upon that website - even though I am signed in.
