This is an awesome server browser made by the same guy who made the Inventory Editor, among other things.
It’s awesome since it negates the need to go around looking for servers and you can server-hop to as many as you’d like with no problem while looking for that perfect server. I really like that you can join the server or copy the address straight from the application and don’t have to write it down like I’ve been doing, heh.
