FAQ needed?

okay so i’m seeing alot of people having the same problems and its drowning out the more rare problems so i was kinda hoping we could get a FAQ started?

for things like the;

Map packs - these are future releases, you will not receive them as soon as you redeem your code but you will get them as soon as they are released.

Specializations - once you have redeemed your code the specializations will show up but will be locked until you reach level 50, if you did not have the code then i think you would have to complete challenges to get them once you had reached 50.

Forward unto dawn - once you have redeemed the code for this you then need to access halo waypoint on your xbox before it will be unlocked on the site

have you seen any other re-occurring problems?
