I knew that Brian Talbot published his answers to Daily Express (and other) crosswords on his website but, until seeing Shaney's post above, I'd never realised that he was a member of AB.
A bit of searching has led to me to his profile though and, given his reputation for helpfulness, I'm unsurprised to see that he posted far more answers than questions:

Although I never really knew him, I'm sure that he'll be greatly missed by many crossword fans.
