clan registering

guys if any of you guys know, do you have to have premium everymonth to keep your clan, or do u just need premium once to create a clan?? and if you only need it once, is a 3 day base pass ok for a premium??

As clan leader you will need to keep your premium all the time, if your premium expires the clan will disband, when the new clan system is released you will be able to make free clans but you will still need to keep your premium.. There would be way too many clans if anyone could make them
