How to count attachments per user?

[timned88]

is there a way to count the number of attachments uploaded per user?  i would like to add it into the display, similar to this mod:
http://custom.simplemachines.org/mods/index.php?mod=1003

i would also like to add it to the stats page and have a possible karma increase per attachment.  is this possible?
