If you want to connect to a server without looking through the whole list you can:
1.Click on the server then hit add to favorites then click where it says internet and click until it gets to favorites then hir get new list.
2.You can also just type in the ip address by hitting ~ then typing in /connect ####### (# is the ip address).
To get the IP address you can just ask the owner of the server, look on its web site if applicable, or click on the server name ONCE then hit server info and it will show the ip address and other misc. information.
