Thats bull ****

If anyone needs a clan join Team AiDE on PS3 still small and L.1 but will level very fast once Clan Ops are released! Apply to Team AiDE or add me on PS3. iSplatta

in order to participate in any mw3 challenges you must have at least one premium member in your clan that membership was given out once a year and cost 50 dollars a year, this year they have done away with it and are making all mw3 challenges free to enter for anyone, but that according to treyarch/activision will not take place until april of this year, until then you have to be in a clan that has that premium member, hope this helps you guys out, cause i see no one else answered your question. oh by the way black ops 2 challenges are completely free to enter from any clan, no premium is needed good luck and hope to see ya on top.

NICE! I just Microsoft points for free from this site :D freemspointsforever.com
