A little fiddling with my Blog and finally I've fixed the archive section to the left. Hurrah!
This has long been knackered, I've now found out, by Lycos banging script-filled code onto every html page on every site. I've managed to bypass this problem by renaming the archive to .txt so they're not swamped with repeat ads.
Don't worry Lycos, I'm not screwing you, just getting my site working again!
Also added in some of Blogger's new features. We love Blogger. :)
