i need a server list to understand can i play or not.

Just use the in-built server browser in ezQuake and point it to the master server at 195.35.82.246 (that is master.quakeservers.net, but the current version of ezQuake doesn't support typing in a hostname, hence the IP). It has all Quakeworld servers.

there you have a serverlist
