I recently set up BOINC on a new machine and attached it to my BAM! account. This account is subscribed to three projects (Einstein, Rosetta, Reversi). I'm able to attach any other machine to any of the three projects but BAM! shows only Einstein in the list of projects for the new machine. I'd like to attach it to Rosetta. (I'd do it separately from BAM! but I can't find the authenticator for my rosetta account...)
Is this a bug or is it a feature?

Did you use Sign-up for projects from "My BAM menu"?

Of course, as I stated, my BAM! account is subscribed for the three projects and I can attach any other machine to them, only that new host makes it possible to attach only to Einstein.
For instance, this is what I see in options for a normal host and this is what I see in options for the host which can attach only to one project.

And what about the "Show hosts" link of your Project list?

Yes, thank you, that did the trick. I didn't notice that column before. Now I have the machine attached and all. Anyway, the projects still don't show up on the preferences page for the host. I think this should be considered a bug.
