Thank you! I took it off my info page, so a lot of people didn't know. I think there was some issue last year with people having 'dates but no years' (as I did) skewing the age data for LJ so that older users (like me - and you, I think?) were under-represented. I was keen not to contribute to that, but also didn't want to be located by pupils, so I didn't feel I could give the full date.
