Decide where and when you want to meet then contact me to make some posters for you. These will advertise the purpose, the date, time and place of the meeting. Put them up in pet shops, supermarkets, library, vets, malls etc anywhere there is a public noticeboard. Talk to the local paper and get them to do an article on you wanting to start a club (preferably before the meeting date).
How's that for a start?
