I believe I talked to you by phone this morning and we verified that the type of problem you are having. We are working on resolving this issue. I'm sorry it's caused a disruption in your classroom.
I'm hopeful that most teachers and students will not get the "Servers Overloaded" error. However, if you are reading this and have the same problem, it would be extremely helpful if you would call me at 425-312-3363 or email at email@example.com. Providing the e-mail you registered with, your username, your school, a phone number, and the tinyurl address that you are using will all be helpful in resolving the problem.
