I am well on with building a society site that is currently handling membership using the Community Builder components and am about to add the CBSubs modules ot handle subscriptions etc. I am impressed with the facilities of K2 though I havent yet learnt much about its e-commerce powers. I have it installed on the site but haven't imported anything yet.I notice that K2 has its own log-in and user lists; How does this intgrate with my Community Builder lists and profiles?
