sudoku.org.uk was Mchael mepham's forum.Wasn't that forum originally on the late Michael Mepham's site? Or am I thinking of another forum?
It was plagued by a multiple spam bots, they didn't develop anti spamming bots like a few people here did to combat it + a few other things, eventually the site conceded to the onslaught and closed the forums down: on-top of that the forums where also aggressively hacked and multiple posts/threads where either hit with spam or out right deleted, which made it impossible to restore content and many discussions where completely lost.
