Why form a club?
1) A club can create a strong identity for a group of people who share a common purpose.
2) Affiliated clubs can apply to borrow equipement from the division for their own events, and lifters competing at international IPF competitions can apply to the division for help with the costs of doing so.
3) You don't need lots of members to form a club - the minimum number of members to be eligible for club status is 10. As your club grows, you may wish to consider adopting a formal constitution, and electing officials (eg a Chairman, Secretary and Treasurer); this can help when applying for funding from other sources.
