ClanBase hosts two kind of cups, OpenCups and EuroCups (often abbreviated to OC's and EC's respectively) starting in September and ending towards the end of December.
EuroCups are invite only cups, with the top teams from the communities being invited, while OpenCups are open to everyone. This season we plan to run cups for 21 games, 5 EuroCups and 51 OpenCups.
ClanBase will be running a NationsCup season after the Fall season, please expect an announcement about it this year. Even though this may seem early, now is the time to start thinking about the NationsCup season.
To prevent the discussion surrounding the scheduling for the next NationsCup we are informing you now that due date for the next season will be the 3rd of October.
Signups are opened today (28th of August) and will close on Sunday the 11th of September
