It is all a matter of perference these days. Here is a nice little run down of the chat servers for you.
Fx server stopped after 1.3.10-Beta13 (which eagle fixed up for us). This is in Archive under eagles name.
WCS isnt available on this site but on another one. Here is the link: http://winmxaddicts.freeforums.org/index.php
. KM isnt making the updates now for this it is someone else.
ZCS is another one and is consistently been updated by Zenar. It is available from here: httpss://archive.winmxworld.com/Zenar/Zenar%20Chat%20Server/
The Winmxworld help room and cafe are hosted on ES. This is eagles own design and is available in Archive as well.
All these chat servers I have used and they all seem fairly easy to use.
Have fun playing around with them and if you need a hand pop into the room. The addy is WinMxWorld.Com Help_13A3F042BABE
