Thank you for this plugin. The best in the field! I use it all the time. No mistakes... I wish you success.

Awesome add on - works perfectly as expected! (when you are smart enough to remember to turn the permission to allow lol) - Great work and thanks for the contribution!
Awesome add-on, just what I needed. I believe this is one of the best and most useful add-ons in XF.
This is one of our most utilized add-ons, making it so easy and fast to identify Similar Threads. The fact you can pick just the same forum, or determine exactly which forums you prefer to exclude is a really nice feature. KUDOS on a job well done!
