Well... first of all I must say connecting here again wasn't easy at all but I'm happy to inform you I have succeeded, as you can see!!
Now don't ask me about the title of this new post, I haven't got a clue yet. A ring was mentioned in an anonymous comment received yesterday. I mean today, I received a notice by email, announcing that a comment had been left in the archives. That particular comment has been deleted in the meantime, by its author presumably.
Nevertheless, I will most certainly be investigating and keep you posted. Oh yes I will!!
