As you all know, the transition from LAVA 1.0 to 2.0 hasn't been an easy one (in part, it's still not complete), and there's been a lot of requests to the moderators that old posts that lost author attributions. There's no easy way to do this, and the moderators currently have their hands full doing some other tasks behind the scene. So, unless you really really really need a post reattributed, it's probably not going to happen (and if it does, it'll be a long time before we can get to it).
