My_Livejournal_Style works -- I'm using it right now! :) It does it by reloading the page, but it would be nice to have the links changed before you click them. And I tried this last weekend, and it does work if you find/replace "style=mine" with "format=light".

I'm pretty confused because format=light is my favorite, too, and I thought that it was the same as lynx, but then, no, it appears to be different on DW, and... I don't know. Maybe it is the same and I'm just confused. /ramble
