In the dim dark recesses of my brain (there are many), I can't help thinking that I once had a pseudo-log-in as Richard Hallet!
(see also Kevin Hodgson etc...)
I wasn't thinking of the trolls, just the duplicates.
I'd imagine you'd be looking at thousands, if not tens of thousands, if you include all the trolls; Doran's probably good for 50 on his own...
