Please take a mulligan

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

Take another "swing".

Type in a different league address:    ???.golfleague.net

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