Mmh, can't say I agree with all points in that translation, but the scan is too fucking bad for me to actually bother to do one of my own.
Anyway, yeah, things somehow picked up in this last chapter. Not only do we know that Deidara is alive (yay!) but that getting a ring is/might be enough to become part of the Akatsuki....
Thing is, I see it like this - you don't challege an Akatsuki member just because. You must know what you're getting into if you even hope to have a chance at winning.
SO lets say you want in, you go and challenge someone, and you defeat him - as a proof you take the ring and then go and I dunno, show it to someone. The rings must have a special something (besides the kanji) on them, a jutsu of some kind... so if you have one it must necessarily mean you defeated someone, and that must give you at least some credit for getting in.
Of course, there must be an extra test.
Like killing your best friend or some shit like that.
