A security issue has been found last week in the authentication protocol OAuth that Fire Eagle is using to authorize its users. The bug is being resolved right now but in the mean time, if you are new to Voilà! and need to authorize it to Fire Eagle for the first time, it will not be possible. It's not due to us, and we are also waiting for a fix for that security issue. We're very sorry, and thank you for your patience!

[UPDATE 04/28/2009] As Fire Eagle explained on their Twitter account, the activations are possible again and Voilà! should work without any problems for the new users. The disclaimer that Yahoo! added on the authorization page explain the underlying OAuth problem that is being resolved for the moment. We will let you know when the problem will be fully resolved.
