It's 3 games in less than 12 months, you become eligible for VCRA defence after the 2 month point (if the 3 games at a site with public liability are complete). Again yet another good reason to research in places with good info like this before making a purchase. Btw I'm posting this largely for the benefit of the lurkers, this isn't a personal attack we all have to learn stuff.
"How do players become members of an approved game site and eligible to buy RIF's?
The games site has to record you as a member and preferably issue you with a membership card.
To qualify as an airsoft skirmisher you must be a regular player at that game site having attended not less than 3 times in not less than 2 months and no more than 12 months."
