How do I rejoin a secret group on Facebook?

[Blahdity]

Hi! So I was invited by email to a secret group (for a college, so I can't call up the person who invited me as I don't know her). I clicked on the link to be brought to the page that said I could join, but I realized that I was logged on under my brother's Facebook, so I logged out and logged back in under mine. Now, under my Facebook, if I click on the invite, I just get to a broken page (though if I log back on to my brother's it works). How can I reset this invite thing? Thanks.

Try to invite yourself via your brother's account or let them know so they re-invite you.
