I think you'll struggle to get 20 people, especially with the comp starting when it does (you'll find the site dies down a lot during the AFL off season, except for the BBL topics). You'd possibly be surprised how many would be interested if you did start a comp though: even though there hasn't been much interest shown to date in response to your post, people would sign up.
I don't follow golf much at all, but I'd probably give it a go, as it seems to involve minimal time commitment. That suits me well at the minute.
Thanks for the response Ironhawk, yeah there doesn't seem to be much interest but who knows, if I build it, they might come lol
I've started a private league called SCS Golf League, it includes the Fedex cup playoff events which start tomorrow of which there are three, Fedex St Jude Championship, BMW Championship and the Tour Championship.
I'm thinking if anyone wants to join now and use these three events as practice to get the hang of it, go ahead because the new season schedule starts with the Fortinet Championship with starts around mid September.
I assume each Fantasy season re-sets when the new season starts because I didn't have the option to edit the schedule in the 2022-2023 season.
One of the main things to take note of is that each season is divided into 4 segments of time, and you can only pick a player 3 times in any segment, so it pays to do a little bit of research to see how the player you want to select has fared in the particular tournament you want to enter them into. I usually just do that by Googling 'PGA Tour results.'
Anyways, here's the link for people to join up so feel free to have a go one and all!

and if you do join, use your SCS name so we know who eachother are, cheers.
