Regarding your question, even if you cannot text to the project page Collaborating would still give you the _privilege_ of being able to add profiles, link to other projects, add media, etc. So it would not be completely pointless, 30 something odd people have already signed on as collaborators to the second project despite the disclaimer at the bottom of the page.
Judging from a comment by Michael McCann earlier today there may actually have been quite an active recruitment campaign to bolster numbers, otherwise how did all those people know that a second project had been started?
