I've got the archives up and running a bit quicker than I expected. The importing was pretty straightforward; it just took a while going through all the posts assigning categories and filling in a few missing titles. There's probably a few links left in there that go to old blog entries on Twoshoes, but that shouldn't be a problem as I have no plans to delete those archives.
Next up: skinning the comments boxes, not least because the default skin isn't behaving 100% right on my machine (IE6 + WinXP). Don't know why, but there ya go. Also, my permalinks aren't going to anchors. That's what I get for doing my own templates from scratch.
