That sounds like fun. I'm already getting the OED word-of-the-day. If they would just lower the yearly price, I'd sign on (so would thousands of others). Why don't companies understand that when you drop the price, you get more people buying? Maybe they WANT to keep it expensive and exclusive.
Color me clueless. Oxford English? If so, very expensive. Like I said earlier, about 10K of English words are derived from Latin. One book I read stated that a basic vocabulary of 1000 Latin words was HUGH. Textkit's vocabulary service is FREE, and you can get as many words a day as you'd like, as well as on-line reviews/tests to see how you're doing. I've seen another site that has a on-demand vocabulary test as well.
