darwinports docs should suggest a step before requesting a commit bit

[fenner@…]

The Darwinports page, ​http://www.opendarwin.org/projects/darwinports/, says:

All contributions are very much welcomed! If you are interested, then either send an e-mail to one of the project leads asking what needs to be done or simply submit an application to join the project with this form. Thanks!

The form that it points to turns out to be the form to request a commit bit. It seems that "If you are interested" should point to "subscribe to the mailing list, submit new ports or fixes via bugzilla, etc" first.
