Information: Log Organiser allows quick and easy management of your IRC logs.

Usage: After clicking on 'Log Viewer' you will see this type of window:

The listbox on the right side lists the logs that are saved in the 'logs' folder of your mIRC directory. Double clicking on any of them opens that log. You can search any word/text in that log by using 'Search Log Text' option. Other options are so simple that I didn't think they need to be described here.
