1.0 link Rainbow Dash Network http://rainbowdash.net/ Bit Shift (bitshift) http://rainbowdash.net/bitshift http://rainbowdash.net/notice/1552079 Seriously though, I dunno how many versions old this feature is, since I've been away from Thunderbird for a while, but that's a pretty impressive thing to be able to do.
