I've taken over this add-on from @Daniel Hood, and it's now available on my site, Atelier Aphelion, for purchase and download. All future versions will be there, as well.

If you have a current license for this add-on, you can register it there (instructions are available here). You'll get a license from me (terms here), for the remaining duration of your original license, plus another 30 days - just a friendly gesture because of the inevitable delays caused by the hand-over.

My plan is to review and update this add-on to address any outstanding issues. Because I've taken over almost all of @Daniel Hood's add-ons, it might take me a while to get to this one.

To improve support, the requirements for this add-on have been updated:

• php 5.4+
• Xenforo 1.3+
