I remember there used to be a simple option to do so, but I can't find it anymore (as league founder). Anyone? Thanks

as far as i know, it is still an option under 'commissioner options' --- once the league is full it will be somewhere in here (this is from a non-full league so it doesn't show up)

Commissioner Options:
- View Rosters
- View Complete League Actual Stats
- Sitemail League Owners
- View Submitted Gift Certificates
- Theme Forum Administration
- Edit Theme Title/Notes
- Make League Public
- Disband League (send all teams back to Draft Center and delete theme league)

League is full, but maybe I have to wait a bit until it "goes live". Thanks jfranco

Check your league options... You no longer get thie choice if you selected the option to "randomly align league" when you created the league.
