I have just gotten around to being able to say I have "figured out" some of Movable Type... the templates are clunky and crazy!  I found this nifty little tool which makes templates and the code is oh so much easier to modify and customize...

But, it did not change the styles for the comments area.  So basically if you click on my blog to leave a comment: 
http://www.xbdsm.com/blog/
You get a black page (my choice) with dark grey text (NOT my choice).  For the life of me I cannot figure out how to change that text;  somehow or other the Movable Type code is actually pulling a default comments template from elsewhere. I think!  |confused| 
Has anyone else dealt with this?  Or am I the only person who has bothered getting movable type which I thought would be so easy and nifty and wound up being a pain in the butt.  (But the blog is starting to look nice!)  I now have a members only blog on my amateur site also that has the same problem... so if anyone has any thoughts, I'd be so grateful!
Cheers,
Tamara
