After completing the Badges 101 and Hackasaurus badges, one is prompted to add them to ones backpack. I provided my email address (arich at moco), but was told "An error has occured please try again later." I was able to transfer badges from badgus just fine last night, though.
My recent experience was I was able to send the Badges 101 to my backpack at beta.openbadges.com , but the Hackasaurus badge at http://toolness.github.com/hackasaurus-parable/navigator-badge/#icanhack failed every time with user is not logged in, redirect to /backpack/login (I filed issue #184).
Sounds like #451.
Actually the first part of the report sounds like it was a Persona problem (we don't issue that error message) and the second part sounds like #451. Either way there's not much we can do.
