Our forums had over two million posts with 17k registered members, but we've heavily pruned them down to about a half a million in anticipation of easing the import to xF.
Any recommendations or suggestions as to valuable must-have add-ons, esp. for a forum of our size?
On a side note, we're in the process of developing a Wordpress <--> Xenforo plugin that meets our needs and will work with Memberpress (subscription plugin for WP @ memberpress.com). So far it is working well, it allows two-way login and logout, with registration handled at WP (via MemberPress). We wanted to migrate away from aMember which had become too problematic for us. If all works well and the code is nicely packable, we'll look into releasing it as an add-on for those needing a more robust WP/XF connection.
P.S. We are especially needing some sort of ad management solution that will let us use our DFP code to ease load on the servers and allow for us to serve up ads based on user level (paid member = no ads), etc.
