Just thinking out loud...
how about some kind of freeroll / learn to play poker fun event/ in a sort of "open night for Nottingham"?
Encourage those who are interested/curious/nervous about the poker world , but are too afraid to go there!
Maybe one section of the club, one evening....so members could bring a newbie friend

Only new sign ups on the night:
Learn to play!
freeroll comp
nibbles/drinks maybe?!
free online voucher
etc
