I was wondering about this, too.  I've had a clan for a couple of weeks now and never received an option for the boost.  We have three other founders and each of them was able to add their boost.  Customer Service said that it may have been delayed.  That's the most I could get out of them.

Was originally a chump member and created a clan, but then paid the 50 bucks over Christmas, so now a paid elite member.  Was given a founder card by a friend that wasn't going to use elite...I currently have Founder status (green skull back ground), but no XP ever got applied to our clan, even though I never joined another clan.  Is this something that's broken?  I know BeachHead still has a lot of work to do with all the elite clan stuff, but I guess I just want to make sure I don't have to do something manually to get my 500 XP for the clan to show up...Thanks in advance for any responses that can help...holla!
