As is always the case whenever this cup is organised (every four seasons, I believe), there’s a discrepancy.
The cup is scheduled to start once there have been 512 entries!

However, only 353 eligible clubs have received a private message inviting them to register
#ranking?type=legends
(a number of which have been inactive for some time!)

So,

• either the Cup will never start
• or the admins will reduce the number of registered teams (256 seems to be the ideal number) so that it can go ahead
• or the cup will start on 11 July as planned, but with several hundred inactive clubs suddenly becoming ‘legendary’, which is a bit odd

But then again, perhaps it’s designed this way so that the number of entrants remains unattainable and the cup doesn’t start before 11 July, when the other official cups will have finished or be well underway.

And just like every four seasons, it’s the same old story.
Yes, there are inconsistencies, but there aren’t enough ‘Legends’ clubs; if everyone wants to sign up for the ‘Legends’, there needs to be enough space.
There’ll always be some people who aren’t happy; if we run it with fewer clubs, those who wanted to take part will come and complain that they couldn’t sign up.
To the sensible admins: if, at the level just below the members for a cup, they see that registration is closed, they’ll simply go ahead and launch it.

For future rounds, it might be worth setting up an automatic filter to exclude clubs that have been inactive for more than x days (56 days?).

Yes, just 256 active ones would be great

And why not create a 256-team cup and restrict entry to managers from the Legends’ Circle?

That sorts everything out: no outsiders, no inactive managers, no prohibitive deadlines.
