FirstLastSeen - Track first join and last part times
Version: v0.10

FirstLastSeen keeps track of a players first join time, and their last logout/kick time, and provides simple commands with which to access that data.

FirstLastSeen also has the ability to important firstseen and lastseen times from Towny, to do this enabled ImportTowny in the config file, once complete it will disable ImportTowny again.

FirstLastSeen supports and is tested with PermissionsEx. FirstLastSeen also supports default Bukkit Permissions! And will support any permissions plugin that does the same. FirstLastSeen also tentatively supports Permissions 2.7.4 and 3.1.x, but is not tested against these.

Translation can be accomplished with the lang file the plugin will create, simply change the wording and place the <date> and <player> tags accordingly.

FirstLastSeen has been translated into German, Spanish, and Polish:

FirstLastSeen will broadcast a message to your server when a player first joins. To modify or disable this feature, simply edit the string in the "lang" file.

If you translate this plugin I would be very grateful if you would send me your lang file so that I may share it with others in this post.
