Yes Al, that was me. The giveaway is the blue ribbon tied my bumbag with 'Tussockface' written on it. The fact that you didn't notice it proves you weren't staring at my bum, which is good to know.
You're right about needing nerve to approach people you think might be on the forum. If you stroll up to someone and remark 'Excuse me, but are you by any chance AlligatorShoes?' (or whatever), and they aren't, they really do think you're mad. At least, that's what they think after they've gone through the initial (and arguably even more awkward stage) of assuming they've misheard you and asking you to repeat what you just said. I speak from experience...
