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 250+ 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.
With so many other developers having done similar add-ons in the past (all of which are no longer supported), it's nice to see that Andy has finally made one that works well along with all of his other add-ons. This is a great little add-on for XenForo.
