I used to use it on vB,I know you can just click on a members name and the pop up box will say the last activity of a member.
But I just liked it when I could see that info in the postbit.
Like in the screen shot;
it shows date when Joined, Messages , how many likes...
I'd just like to have an extra part saying somthing like: Last Seen: ****** or Last Online: ****
Has that been done yet as an add on?
