Greetings. Please enter the full internet address and a port number to any
machines you would like to be polled on for gung fu competitions. The first
two fields are required and the last one is optional. 

I have made a guess at the fields but be sure to give full internet addresses.

--> Separate fields with at least one tab or space (no maximum).
--> Save the file with C-x C-s when done. This is important (:-}

Zaijian!
