Bit late, but it's been niggling for 2 weeks now. Couple of Saturdays ago my main choir ran a 'come and sing' day. The work was the Mozart requiem and it was very successful.
I tend to act as platform manager for events like this (I can project my voice and be heard) and as an ex-chairman of the choir, I tend to do 'meet and greet' of guests and the audience etc.
Whilst we were assembling before the concert a lady approached me that as far as I know I have never met. She said, "Oh, you're xxx aren't you?" To which I said "Yes." Then she said: "Didn't you used to be the moderator of xxxforumxxx?".
The answer to that would be yes, but not for about 6 years (private forum with moderator teams).
I have no idea who the lady is. My name she would have got easily from anyone at the event, but how she linked my name to having modded a forum for a while back in the early 2000s beats me. Why go to the length of telling me this but not saying anything else? Odd.
There, it's been bothering me.
