Maybe someone already discovered it, but via the menu item “Tournaments” you can also find dates and dates of currently known queer volleyball tournaments, if the league match days are not enough for you. Or you can click directly on this link: Tournaments.
Do you miss a specific tournament? Or is the information about one of it wrong? Then send an email to Dirk via digital[at]schwuleliga.de, then he can add it to the list or adjust it accordingly.
Check the page from time to time, perhaps there is already a new tournament in the list, it’s worth it! Have fun!
