How/do I need to Add my Bronco Nation Member Number

So I made my reservations for the Nevada October 30th Off Rodeo and when I did I did not have a member number so it is not attached to my reservation. Since BN is doing a take over and I have joined BN do I need to add my member number to get added to any cool extras BN might be doing. If so how? I did go in and try and edit my reservation but there was not a spot to add my member nuber.
