on the homepage http://noobs-r-us.co.uk right side teamspeak block you can press the "Noobs R Us TS3" title to join it and by rightclick and "copy link location" (firefox) you get ts3server://126.96.36.199?port=9987 so if you want to add port manually to connect your Teamspeak 3 prog you connect to 188.8.131.52:9987
I recommend you add it to your teamspeak bookmarks after you have joined so it makes it a lot easier to connect via the bookmark. This way you don't need to add the IP everytime.
Also when you are on if a member is on they can give you admin rights on TS or a heed can do it. After you get admin rights on TS you can join the admin room and for example kick or move someone if that is necessary in TS. (never had to do that yet).
