I just joined PowerCore, so I'll share how I was invited. My partner was a member when he first started his business, and he often shared how much PowerCore helped him grow his business. When I decided to start a business of my own, he encouraged me to join PowerCore to fine-tune how I talk about what I do, to make connections within a supportive community, and to generate more word-of-mouth referrals. I think asking a question related to any of those three reasons could be a good entry point to conversation with someone about visiting.
