Charles: a knob, or [censored]?

Get your vote in now. Is he a knob, or a [censored].

That's not very nice Bill, if you can't be a little more civilised I
may have to consider "trolling" *you*!! ;o)

Given that there is only me and a couple of others responding to you,
and despite all your constant jumping about, all the rest of the Group
have you "killfiled" as it is not difficult to find a constant in all
your stupid posts, so none of them can see your idiotic rants and
haven't a clue what you are posting.

If I and the couple of other people who respond to you also "killfile"
you, then you will be talking to the ether. You should be a little
more circumspect you silly old fart or you will end up with no-one to
play with at all!! ;o)

Have a great weekend Bill - you know I will!! ;o)

TFIF!!

TTFN!!

I vote Knob.
