Cool! I just realized that the database server I use has a "sounds like" function that allows you to match terms that sound alike, not just exact matches. I have implemented this in the sea turtle glossary. The upshot is that the glossary can now match search terms that you enter even if you mispell them (to a point ).

 Give it a try: bathemetry

Now I just need to figure out where else this feature might come in handy...
