The idea of this plugin is relatively simple. It allows administrators of a server to check:
There is no configuration needed to use this plugin! (Unless using MySQL)
The only command in this plugin is:
/firstconnect <playername>
/firstconnect: fc.lu

As of plugin version v1.5, FirstConnect includes Hidendra's plugin metrics system. This will allow me to see what version of FirstConnect/Bukkit people are using amongst other things which will allow me to make sure I support versions people use. None of the information provided by metrics is sensitive nor can it be used to identify your server.

If I plan to release a new version with big changes, it will most likely be available to read about here.
When the plugin first loads it will try to import existing dates from player.dat files, this may take a while.
