Hit Hack (6.3.x) Last Reply By In Forum (6.3.x)
As you can see, both of these hacks are for 6.3... I believe there are 6.2.x versions, but if you still have access to the Infopop Members' Area, I'd suggest getting 6.3, to save... getting left behind.
But if you're sure you want 6.2.x versions... Hit Hack (6.2.x)
I don't think there's a Last Reply By In Forum hack for 6.2.x (If there is, someone please correct me...)
Heh, love that icon. Allen, mind if I use it for my UBB? Pleeeease?
