If your club have announced that they are initiating or running a league through Nettla, you can go to their Club Home Screen in the app. The league should be visible already on this page, or you can press the (+) button in the lower right corner and find Leagues as one of the menu options.
Once you are on their Leagues page, select which league you are interested in, and read the ”about text” that the club has posted. On this screen, you are able to:
a. Join the league if registration is open and its not full, or
b. Join the waitlist of this league if registration is closed or the league is currently full
