I am thinking of making a site were Apartment Owners can form a group for particular apartment and discuss there. Let says abc apts, bcd apts, efg apts... one person from ABC apts is allowed to create a group and invite all ABC apt people to discuss and share things and like this bcd and efg. (Hope i made it clear) I know Facebook have groups but i thought of a site for it. Do you think it is achievable? If so what platform do you think will work?
