Project Mechanics is now an international site with the addition of www.projectmechanics.co.uk . Actually, it is just a domain that points to the same content a www.projectmechanics.com, only with a different template. I have been investigated some new tools lately which show some promise, among them are Sothink DHTML Menu. They include samples on how to hook it up to a database, their UI even helps you generate the necessary code. I was able to plug their menu into my site in about an hour, much of that playing with all the settings for the menu.
