So every user can commit only to 5 sites on Area51. If a site I committed to reaches private beta/public beta/final release, will I be able to use commitment I spent on that site again? Or I can only commit to 5 sites ever?
So the moment it exits beta, your commitment should be freed up for use on another site.
EDIT: We changed the way this works. Once a proposal enters the beta phase, your commitment "token" is only freed after the site exits beta.
