I like your top banner: "Free Online Dickionary"
experment with colors.,.. >> I think Brown would look better then red for the top banner ...with a brown stip instead of the redish strip that is below the logo..
Advise: change the drop down menue names to a bold blue to be able to read them better.
The site looks good..and more advanced
Information is power and currency..and a definition site is information that i more valuable then gold.
power means peace
