@lulucrypto, the test site currently is not showing any stats anywhere, neither on a global scale such as https://bitcointalk.org/index.php?action=stats, nor on a personal scale such as the extinct general personal statistics (accessible from the user profile, but disabled since the last hack on the forum).

Any idea if there is a module or a parameter in Epochtalk that current may display this/any kind of statistics? Thanks.

I have seen a "posts over time" chart on an image here: http://epochtalk.org/index.html, as part of the profile information.
