This is an incredibly useful mod that I'm grateful to have found. It is great to be able to see who has read your threads, and when they saw them (to see if it's likely that they read your post within that thread).
Fior a site admin with OCD tendencies, it's an unbelievable tool to see where your users have been. By using phpadmin, or even just entering sql queries directly in admincp, you can easily see everywhere someone has been:
Code:
SELECT * FROM `whoread` WHERE userid = 121 order by dateline
will return all records of where userID 121 has been, in date order. You can then go to a browser window and type
"http://www.yourforums.com/forums/showthread.php?t=21138"
and substitute one of the threadID's you saw in the SQL query for 21138. This makes me think that if someone has some free time, it would be a great addition to the admincp to create a panel that does nothing but this. From that panel, you could click on a username, and it would bring up a page with the list of threads they've visited, which could then be sorted by threadID, date, whatever. You could easily find out how people are navigating through your site, in order to make conscious decisions about how to streamline or improve that navigation.
