Oh, I'm just gonna put my review here, so someone may use it as the guide as well.
Alright, I put your site thru the validator and we have this: "Failed validation, 23 errors"
Your html pages have "XHTML 1.0 Transitional" type, which is standard now, and it's good.
Errors:
1-2) just remove that meta tag with name="verify-v1", you dont need it anymore, you've passed Google check up.
3-5) depreciated attributes (ignore, or move to DIV layout from table layout)
6-48) ignore, for some reason, the URL encoded string was not ignored
49) This is a serious one. You cannot have <DIV> tag inside a paragraph <P> tag. Try to remove surrounding <P></P> tags
50-55) ignore
56) same as 49)
Actually, you dont have that many serious problems in markup, but better to fix 49) and 56).
Your next step will be installing other browsers and see how does it look there.
However, if you are considering to use Wordpress, then you even may not need to fix those errors, most of the Wordpress themes are W3C compliant.
