Thank you for this free XF2 version. I used the RainDD version before. Xon is one of the most trustworthy XF developers, all his addons can be installed blindly, as everyone knows: it will work and it is safe.
With this add-on admins receive more insight in how many users actually read and stay in specific threads. As with all add-ons from this author, fast response and support combined with quality code make this add-on a very valuable extension of core XF.
Absolutely great add-on, Xon developed some of the extra options for us with ease and my server or page load does not suffer from this (mysql). Members love it and increases activity on the forum, people do love to see where everyone is at.
