With the main server doing really well right now the etpro guys have set up a ETL Campaign server so if you fancy something different give it a try.

We also still have the Beginners server which also is something different if you can not connect to the main server

Please make sure you all try to connect before the night. I have just tested with my legacy without any issues but i know this may not work for everyone.
As for the time people have to connect the server will be up all day so you can connect anytime you want
