[HELP] as easy to run multiple servers?

If you want to run multiple servers you just had to change the port...
Example:
123.45.678.9:8303 -> 123.45.678.9:8304
But you need to edit your config.
If you mean something else i dunno what you want. Oo

Sure it is, just start your servers with the following command:

teeworlds_srv1.exe -f server1.cfg

if you now want another server with another config write:

teeworlds_srv2.exe -f server2.cfg, etc

You could also try

teeworlds_srv.exe -f <config> "sv_port <port>"

if you want to run multiple servers with one config.
