At least I’ve got something going for me:
I’ve since gotten a “supermaster”, which I think is higher. It took me a while to figure out that Make-a-Word was not Boggle.
However, I’m not actually that dumb:
I believe Supermaster is higher, yes. There’s also “Living Dictionary”, which think_too_much managed to get, which is above that.
And then there’s super dictionary. Laura and I both got that, but it’s probably not worth the time.
