If it wasn't for the fact that we're knee deep in two other major
projects for the infrastructure team right now, I'd be all over this
:-) But we really need to complete that before we put anything new in
production here.

What I'd like to see is one that integrates with our general layouts.

Also, I tink one of the main issues with the archives today that
people bring up is the inability to have threads cross months. I think
that should be fixed. Basically, get rid of the grouping by month for
a more dynamic way to browse.
