[Overhaul]

Edit: didn't see the link. Hold on.

Edit 2: For one, the indentation is awful. Two, you are not returning the formatted IP in your GetStampIP function.

PHP код:

stock GetStampIP(playerid) {
    new S_IP[16];
    Join_Stamp = GetTickCount();
    GetPlayerIp(playerid, S_IP, sizeof(S_IP));
    return S_IP;
} 


Edit 3: Why is Join_Stamp there?
