Thanks. I purchased and installed this add-on and it works great. I just converted my vB4 forum to XenForo 2.0 and missed the "Who has read the thread/forum" info I used to have with the vB.
The only thing this add-on does not do that the vB4 did was with vB4, I could click below on the list of people who viewed the thread, and it would bring up a list of those viewers with the time that they last viewed the thread. That was nice, so if that can be done with this add-on it would be a welcome addition. Sometimes it's nice to know when a certain member or group of members actually last viewed a thread.
Other than that, it's perfect. I recommend this add-on highly. Great job!
