Pinging a server

Is it a Hamachi server?
if so, PMC cannot connect to Hamachi servers, in order to 'ping' the server as online.
In this case, add a note to the server post stating the server is online.

if it isn't a Hamachi server, have your server running, then go to your server post, click on 'update this server', and then hit save, and that will make the connection between PMC and your server.

i meant so that it says it is online on pmc :S

Add it to your list of server on mc

If the server isnt online then it isnt green...
