Uppercase sensing?

I admin a forum at work, and it is based upon Perl.  Now, I have some users who can't seem to find their 'Caps Lock', and turn it off.  I know it sounds silly, but it is a pet-peave of mine that people type in all caps.

I know that Perl has a lc( EXPR ) function, that will return an all-lowercase version of 'EXPR'.  But I don't want to run that on all the posts.  I only want to run it on the posts where everything is in all capital letters.  I realize that this means that good grammer is thrown out the window, but they started it! ;)


How can I read if string $post is made up of all capital letters?
