Autorank bukkit plugins 1.6.4

Autorank is an automatic ranking plugin that allows you to set rank-ups that have requirements. You can createrequirements that make certain a player has at least x amount of money or x minutes played.

An example:

A player starts out as Guest. When he has played for more than 10 minutes and broke at least 10 iron ore, he will be ranked up to Member where he can do a lot of other things. Then, when he has played for a couple of days and earned 1000 money, he will be promoted to Trusted; a group that allows him to do cool stuff. This can go on for as much ranks as you like. The possibilities are endless! It’s up to you!

Autorank 2 is currently in beta mode. It is tested extensively and we try to make sure everything is working. Although we test our builds a lot, some bugs might find a way through.
