Sorry for this stupid question!

For the first time in many many years I've grown sweet corn.

I can not remember how you tell when it is fully ripe and ready for
picking. The tassle thingy has gone brown right down to the plant, so is
it ready now?

Can they be left on the plants until required or do they need picking
and storing/freezing (obviosly they'll need picking before the frosts!)

Thanks
