1. Disappointment - its not Dungeons and Dragons
2. Quite like the look but 36 validation errors on the front page alone

nice site ... looks so professional ...
a favicon would be a good addition ...
and check your site using browsercam.com to see how it looks on different browsers ... and resolutions

You really should split up all of your different webpages into physically separate pages. At the moment they all route via index.asp, using query strings to specify which page to display.

This is bad SEO - search engines prefer straightforward pages with no query strings. There's a lot of speculation as to whether or not pages with query strings can actually receive a PR (Google page rank) or not... so to stay on the safe side you should split them up into different pages. This would also give you the advantage of being able to put page-specific keywords into your webpage filenames.

You don’t have to redesign your site to do this; you could just do the following if you really wanted:

For your ‘market trends’ page, for example, you could create a new page called ‘market-trends.asp’, then just insert the following line of code into it:
<!-- #include file=" index.asp?src=mt" -->

Apart from that, I like it

Professional site.
If you want ot SEO maybe separate javascript to other js files and insert meta description, it should be great.
