Right I see, didn't realise how much voluntary work is put into the club until recently.
Another thing to do, though which may actually serve to be useless but I do often see it would be to go before a lecture in somewhere like Th. L with a free jersey and say "First one down here gets this" along with an announcement. Of course that would require the club donating free stuff and the embarrassing act of doing it. I once saw this happen for free tickets to a night out or ball or something and no one went for it. :o
