You know that's not how this works, right? That site just copies master2.blockland.us, and whether your server is actually accessible has zero effect on it.
I know, but this method worked for me. Though the way I found out was accidentally.
I was frustrated nobody came to my server when I disabled UPnP (long ago) so I decided to find a service that allows me to view the server list. There was the one I linked (that I found out later) and the one at Cohort's website (the clan). And my server wasn't there. No matter how many times I WebCom_PostServer()'d.
As soon as I could get players, however, my server was in the list clear as day.
I haven't a clue how this worked internally, but it did.
