Maybe you should share that information with the database... :)

It's something entirely different. The only thing in common is the word
"find". There's already a load_or_save() Helper method, but with the word
"load" in there, it of course needs a unique key. I think I'd have to see
some more requests and usage examples before adding something like the
db_find_or_create() method posted earlier. Right now, it seems very odd to
me. What does everyone else think?
