Well, when the mod is installed, when I (I haven't tested this with a regular/test user) click on the online users link (the one that tells you what everyone currently browsing the forum is doing

), every single registered user is reading their messages

... which, of course, can't be true

... not that I've got like 100, 200 users online at that time, but even if that number is 5, it seems very unlikely that they'll all be reading their messages at the same time... and then suddenly stop doing that when the mod is uninstalled

.
This happens every time I click the online users link... they can't all be reading their messages at the same time, every single one of them, right, LOL
