Can I refer someone without committing?
It seems like the only way to refer a friend to a proposal it to commit to it, refer the friend, then uncommit to it. Seems a bit daft. Am I missing something?
During the commitment phase, you should be evangelizing the site proposal, and referring others via the widgets we provide.
There should be a commitment sharing link as pictured -- assuming you've committed yourself.
You want to share commitment without committing yourself? Then just copy paste the URL to the commitment page, I suppose..?
