Allow non-paid users to have public keys.
Short, concise description of the idea
Public keys should not be limited to paid users.
Full description of the idea
There seems to be some sort of assumption by the development team that public keys are only useful for people wanting to make submissions via email. I have no paid account but it would possibly be useful to my friends if my public key were listed somewhere other than the current 'best bet', which is listing it in the Biography.
I would propose also moving the entry of the key to the userinfo page.
