[Zope] How-To: Dropbox date entry for html forms

In building my first Zope site and training content providers to use the management interface, I quickly encountered requests for an easier means of entering dates (as opposed to the default "1966/09/30" format). I've written up a quick How-to that contains a DTML utility method for incorporating droplist selectable dates in html forms. Before I make it (more) public, I'd appreciate some feedback. Any objections to the implementation? What do you think about placing short utility methods in How-To's rather than Products? http://www.zope.org/Members/darran/select_date Cheers, Darran.
