I find that the tool is quite useful
You can get many recommendation on how to improve the security or solve the problem in your Joomla installation.

With the followings features, I can say that this extension delivers a satisfactory PMS:
* Option to notify the user about new PM
* Option to see list of user
* Option to pm person from his/her CB profile
* and may others

Further improvement might be done if:
* The message (to be sent) box is wider
* Shorter period to send the "forget me not" message e.g 7 days or even everyday
* captcha

I am trying to find a related item module, which can display item based on title.
Most of my content don't have sufficient meta data (I know, it is a fault), but it happened already.
Therefore, I need a module, which can show the related item based on title or anything in proximity

This component is such a good one.
I am really helped.
However, it lacks some important features as follows:
* No possibility to export the statistic data so that it can be processed offline
* MySQL database tends to grow pretty fast even with low traffic web site (50-100 visitors/day)
* As pointed by carloq, the last part of path (subdirectory) is doubled; Disturbing the statistic calculation but annoying
* No automatic feature to disable recording statistic from web owner computer, hence the web owner cannot visit his/her own web site without adding number of recorded visitor.
I had to make the hack myself, but I love to have the feature built into the component.
