Having only been a member for a few weeks I have not yet had the chance to invite anyone to powercore yet.  However, I would ask them first if they have the capacity to bring on more business than they currently have.  If they do and are looking to increase their client base then I would explain to them what Powercore is and its benefits.  I would explain how effective Powercore has been for my business in just the short time that I have been a member.  This question will come natural to be able to relate it back to personal experience.  If I have not experienced something personally then the topic or question is very difficult for me to bring it up organically and speak on it with any sort of reverence or enthusiam.
