I am looking for a bridge between Xenforo and phplist (www.phplist.com). I would be willing to pay for this.
I need a separate field to be checked by the user while he is registering in the xf forum and a kind of synchronization between XF and phplist user-db (only emails, username and whether he wants to have the newsletter or not).
Should be independant from the already existing option to receive emails from admin with XF. I have phplist on my own server installed.
Phplist is a free open source software by the way. Very professional for very large newsletters.
