Please take a mulligan

That was an errant "shot" - or rather,
request for a club website that does not exist.

Take another "swing".

Type in a different club address:    ???.golfclub.net

Example: If your club address is abc.golfclub.net ...
Type abc.golfclub.net in your browser address bar.
Do not type in www.abc.golfclub.net, there is NO www in front of a club address.
