What is the best way to handle e-mailing / list building integration with vBulletin?
What is the best way to handle e-mailing / list building integration with vBulletin 4.x? In other words, I would like it so when a user registers on my vBulletin 4.x forum, their information gets saved to a third-party e-mailing service. Some examples of these services include AWeber, iContact, Constant Contact, GetResponse, MailChimp, VerticalResponse etc. I would prefer to use AWeber but any information about integrating vBulletin 4.x with any other e-mailing service would be helpful as well.
