Hello Mark,
This is just my opinion, and please ignore it if it is not relevant.
I think the basic colour for this website looks too cold, and the fonts are a little small....
There are too many push buttons. For eg, just on this topic page, I have a row of optional buttons, including Feedback Forum, Comments, Site Ideas, Opinons (wrong sp), Suggestions, all of which are really about the same thing....
There are too many sub and sub-sub headings. One could get lost in the labyrinth.
The name of this website International should be fully spelt out. Anyway, the shorthand for International should be Intl.
You need a guffaw icon (just kidding)....
