I think any claims to be a student should be taken with a pinch of salt (although there are a few who could convince me they are on a bricklaying night school course) along with I love my job claims.
Certainly anyone who has been on AW for a few years must have finished by now (Masters, PhD and Diploma students excepted) but a few ex-students may be about. I have only ever been convinced twice about a girl claiming student status, unfortunately none active any more -one was in Montreal who after an overnight changed into her day clothes and went off, books and all, to College Lasalle, a private college, up the road. Her Dad had cut off her allowance and she compensated by becoming a 'courtesan' for $180 an hour.
The other was Romanian in the UK who had her study books all over her table -it was only when i looked and saw the books were for her Baccalaureate that I was prompted to ask for proof of age (she was 19).
Certainly intelligent conversation is not a great indicator of student status.
