Point of note - string-titlecase does both the upping and the downing  
of case, which may be a good or a bad thing depending on what you're  
trying to achieve:

     (string-titlecase  "Welcome to PLT!") ; => "Welcome To Plt!"

For what it's worth there's a variant in unlib.plt called "string- 
titlecase*" that only does the upping part:

     (string-titlecase* "Welcome to PLT!") ; => "Welcome To PLT!"

I've found this useful from time to time.

Hope this helps,
