I'd suggest to make it possible to suggest words for adding it to
the library.
Then the moderator of those suggestions decides if the word is ok or not.
$0.02 given.
***EDIT***
I just noticed Firefox 2.0.0.3 has Spellchecking enabled... didn't know that because I personally still use 1.0.7 (for the more user friendly user interface.)
Lock it ^^
