I'm sure John will restore both lists presently, but just in case, these are the cached versions of “Units of Language�?—I don't know what the other list was. Adding words automatically is reasonably easy using iMacros.
PU, can you email me (firstname.lastname@example.org) the names of the lists, and I'll look for them directly? Very sorry you're they've gone missing, but I feel pretty confident they still exist and haven't been permanently lost. Will look into it as soon as I have their names and verify they're still in the db.
