Nice work there, XHTML rules :)
There is a problem with it on the website, though:
Web/engine/page.inc, line 142 has border=\"0\" on the img tag for "support this project". That should be style="border: none;" in XHTML. Otherwise, the page validates fine.
Tim?
Yes, he is right! I will fix this, but I am currently moving to a new home, so my time is a little bit limited in the moment...
Committed to SVN (In Revision 339) and put online...
Thanks for this bug fix!
