vB3 Add Aweber form to header?

[محروم.كوم]

Hello All, I've searching the forums/internet for a few days and checking out de vbulletin files themselves too.. but I can't seem to find how to do it.

In WordPress I can do about anything, but with vBulletin I'm lost


Can someone please tell me how to add an opt-in form (Aweber) to the page header? What file do I need to add the code to?

I don't believe it's impossible although it sure looks like it to me a this point..
Thank you! __DEFINE_LIKE_SHARE__
