Regarding using XHTML - here is some food for thought why not to use it :}: [add www before the links]

I'm not tech expert but it may be good reading for the minibb team.

There are many variations of XHTML available. We have chosen xhtml1-transitional at this moment, it allows to combine old HTML stuff with XHTML compliance, that's what we would like to achieve. We can't imagine such things as xhtml11 or xhtml-basic and specially xhtml strict with miniBB. Maybe we have old-fashioned tables code, but at least, it works in most browsers, so tables structure will be kept.

oh, OK then :)

I've spent 2 days & nights working on XHTML compatible templates... now they all are available on minibb.com here. Forthcoming release RC6 will be fully XHTML 1.0 Transitional compliant... you already may check this out.

:-)

Additionally, miniBB.com main site is now XHTML 1.0 Transitional compatible, too. RC6 release is on the way and will be available this week.

Good, you know i'm waiting for it ;). I know it's very hard to have ALL your code validated at w3.org - so kudos to you!
