BlockConsoleMessages

Hmpf has updated it.
BlockConsoleMessages - Blocks defined messages from appearing in your console and log file.
Version: v0.2
Version 0.3 beta information at the end of this post.
This plugin enables the server admin to filter messages from the console & log file or log them to separate files. It is the bigger brother of BlockCantKeepUpSpam.
If you just want to block the "Cant keep up!"-spam BlockCantKeepUp might be the better choice.
However, if you want to have more control over your consoles & log files content, this is your plugin.
