Got a server up and running, although it is only available from around 10pm UK time. Its "i3D.net - TOXIKK #741620"

Some things that are needed for those of us renting servers :

See MOTD message when you click on a server
Add servers to some sort of favourites list
Copy & paste IP address (and password) from the clipboard

Better than copypasting ip address and password, you can create a steam join link to your server.
Format is: steam://connect/ip:port/password
The port has to be the query port, not the game port. Should be something like 27015 (instead of 7777).

Cant use a steam join link ingame though (unless you use the join game in the Overlay). The copy & paste thing is for directly entering IP addresses.

Simple things like this to make it easier to connect to private servers and your favorite servers. I hate games that don't let you copy paste!
