Thanks again for all your help.
I had originally posted the tournament on my site as $35 (for ams) -$10 if you are a PDGA member. This is how the PDGA tournament standards info sheet said it should be done.
However, it IS confusing, so I changed it after you brought it up. I don't see any of the other TDs following this confusing standard either.
Just to be clear:
The fee for all Amatuers to play is $25. There is an additional charge of $10 by the PDGA if you do not have a current membership. The PDGA fee for non members is a requirement at all PDGA sanctioned events.
I hope that clears up any confusion.
