Yep, this was all a joke. April Fools! The Test Exchange isn't in trouble. To be honest, I never expected any tests, let alone nearly twenty, to be uploaded because of that one post. I think we learned something yesterday: Most of us have the resources to be very helpful on the wiki, but a lot of people never actually get around to helping out. Does it really take an (empty) threat of taking away the Test Exchange to get you to be helpful? Prove me wrong. Don't stop uploading tests now. I want to see how many we really can get in a week.
Also, don't be mad and take your tests down because you were tricked into doing the right thing. Instead, I strongly suggesting bragging about how you were helpful in the Test Exchange's (fake) time of need, while everyone else wasn't. Good job!
Oh, and one other thing- the Division D was an April Fools' joke as well, but I assume most of you figured that out. It's such a shame we have to wait another year before we can do something like this again.
