I am developing a paid business network which will have local chapters and regions where members will communicate amongst one another at both the local level and nationally. It will act as part social network and part messaging system among members... plus some other things. What is the best script to use to set something like this up?? I have been looking at Vbulletin and SocialEngine. Anyone have any recommendations as to which may be better?... or other suggestions? I played around with Ning but it's too unflexible as far as design. Tks
