I just re-edited my homepage, TSSG WIT: Mícheál Ó Foghlú's Home Page, to make it HTML 4.01 Transitional valid. Not too much trouble. However to make this weblog itself (i.e. the index pages and entry pages) XHTML 1.0 Transitional valid is much trickier as there are often "&" symbols buried in URLs that I just pasted in when I posted a link (and the odd one I typed myself inadvertantly). I've left it on the long finger for now.
