SignMonitor is a lightweight plugin that logs all sign placements on your server. It's designed to detect players who are breaking the rules (inappropriate language or advertising, for example). Whenever a player places a sign, the following information is recorded: player name, location, and sign text.
All sign data is stored in /plugins/SignMonitor/signs.txt. Data for individual players in stored in the /plugins/SignMonitor/players/ folder.
To install SignMonitor, simply drop the JAR into your plugins folder and (re)start your server. No configuration is necessary.
SignMonitor is open source, under the BSD license. You can find the source code on GitHub.
