How can I stop auto-joining the 'Rookie Help' chat channel?

Every time I log into EVE Online, I am autojoined to multiple chat channels including 'Corp' and 'Rookie Help';

How can I change it so I no longer join the 'Rookie Help' channel?


After your initial thirty days, you will no longer be able to join Rookie Help.

I don't think it's possible to stop autojoining the channel prematurely; the best you can do is to manually close it every time you log in.
