Unlocking Specialization HELP!?!?!?

Can I still get the specialization code from my e-mail account while I’m a silver member? I already use the XBL 14 day gold trail since launch day I already rank SR70 so I can’t unlock anymore specialization right? after Nov.20 343i or Microsoft suppose to sent the specializtion codes for those who have standard edition who play and participate Halo 4 BEFORE Nov. 20 to get the code, So heres my question am I suppose to get the specialization codes if I’m a Silver account member or GOLD MEMBERS ONLY?

I’m pretty sure you’ll get the codes.

Btw, has anyone gotten their codes?
