Firstly, Id get your numbers to enable a EGM and before seeking that first have an informal discussion among your leaders within that group to ensure you are all on the same page, know what you need to know, and what you collective want to achieve, and to help build your numbers – which may even include some current committee members as most decisions are not 100% votes in favor. Someone needs to lead it, so if that’s you I’d suggest you don’t run too far in-front of the others and be open to the groups various thoughts. I imagine getting many of these folks active and involved will help cement them in place. When you are ready to roll get the show on the road seeking your EGM but if you can’t get the numbers informally you might find that is the first thing you need to acheive.
