Welcome to XF2 Addons. You can buy my Premium membership for $35 per year, and this gives you access to download any or ALL of the 335 add-ons that I have developed for Xenforo 2.x. In addition, Premium members will get technical support. Once the Premium membership has expired you can continue to use the installed addons on your forum as long as you like.
Could you please add an option to create an threads on a selected forum when a they have a duplication account ? Also, could you please made their registration in pending until a moderator review it ?
