ChatBox Message

In the one ChatBox I saw this message:

*user reached xxx posts

The message come out whenever a users had a hundred posts, and on every hundred posts.
I like that and ask you did someone can make it?

Thanks in advance!

Regards & Respect!!!

Hmmm.... Anybody?
Thanks!

It's more like a notification about someone's PM box being overloaded. @smejker , Is this still needed? Solved?
