Posts read hack

Was wondering if a hack existed to be able to track the amount of posts a user read? Or if somebody would be kind enough to throw one together quickly. Thanks.

How many they've read?? That could be thousands (especially if you have a long thread with 1000 posts).

Can I ask what you could use this type of information for? (just curious)

Ooops, meant how many threads they've read :) I was wondering if it was possible to track the amount of threads read so I could use this information to prune out users. I help a friend run a private forum that would like to remove the users with low posts and high counts for read threads.
