I've installed on use.perl.org the code that turns your comments and journals into valid HTML 4.01 strict. The surrounding HTML is not, but the comments and journals themselves are.
Or should be.
If you notice any big problems, let me know. I had some issues with character references, but a sampling of TorgoX's journal entries with Unicode in them showed that I appear to have gotten those fixed.
I had most of the problems recently with URL handling, mostly because I was not concentrating on those but the tags themselves, and some errors crept in. Those should be ironed out too.
Probably next week I'll begin converting old comments, sigs, user bios, etc. to valid HTML. Maybe even stories. Journals don't have to be converted, as they are rendered on display from the originally saved HTML.
