Time to reply, eh?
To be honest I would love to do this, the only problem is I don't know how.
Sure it's easy, I can just add a query to the getpostbit() function, but that would really slow down display of showthread, and I'm not willing to make that sacrifice.
Or I can just store that number in a user field, but that would require updating it on so many places or it won't be accurate.
I'll probably use the second method, beta test is until I can make sure it's working fine, then make it publicly available.
But it will take a while, I still have a lot of stuff to do on this board.
