MessengerLog lets you monitor and record the chats occurred in any of the popular messengers in plain text and HTML or rich text formats. MessengerLog can record from MSN/Windows Live messenger, Yahoo messenger (both including the 9.x version), AIM/AOL and ICL (both including v6.x ), GTalk and Skype.
Apart from the text itself, the software can record emoticons, fonts colors and so on. As soon as MessengerLog detects a new chat session it starts off recording in the stealth mode. So you don’t have to keep the program running in order for it to work.

MessengerLog can support multi user system too.
The improvements in the 360 version include auto chat log uploader, via email or FTP, a tough chat log file manager, advanced chat log search engine and more. In the current version of MessengerLog 360 feature improvements in two areas, the rich chat display and the error log.
An organization may need it to keep a record of the support provided through IM. If you are a parent it will help you control and monitor the chats on the system.
