Clubs for the most part are for functions like parties, events and so on. I know I have one club that I'm in all the time from a party chat perspective. We can chat no matter where we are. I love that feature.
i just made a club the other day, i find it pretty cool being able to have people come by when im not around or visit while im watching something on crackle, my club is called GooDTyMeZ tag is goodvibe
