1) Load ur wc3 + bnet.
2) Open up ur banlist.
3) Join a game and to check for ping, depending on the settings
which u set it to, it could be, "//pingall or /pingall". On the top
of the screen, there should be something like, "Querying IP
database..", after that the ping of the players would come out.
Once u see it, just ctrl+c and ctrl+v to the textboard.
