  69 <p>Here you can register a user. You need to register a user so that it can be granted push access to project(s). SSH is used for pushing (the git+ssh protocol) and what authenticates you is your SSH key - there is no password (though we recommend that your SSH key is password-protected). You can find your public key in ~/.ssh/id_rsa.pub or ~/.ssh/id_dsa.pub; if you do not have any yet, generate it using the ssh-keygen command. You can paste multiple keys in the box below, if you wish, each on a separate line. Changing the keys later is not implemented yet - if you need to do that, please contact the administrator.</p>
  70 <p>We won't bother to verify your email contact, but fill in something sensible in your own interest so that we can contact you or confirm your identity shall the need arise.</p>
  71 <p>By submitting this form, you are confirming that you will push only free software and no content that would violate any law of Czech Republic. Have fun!</p>
