試了公司的和gmail，都未果。錯誤信息如下：
We are sorry, but we are unable to complete your request.
The following problem(s) exist:
- We are unable to qualify you with the email domain and program code you have provided. You are likely no longer eligible for the program. If you feel you have reached this in error, please confirm with your benefits administrator that the program code and email domain being used are correct.
關於需要提供工作email，是這麽說的：
The terms of this program require that you have a valid e-mail address with a participating company. AND You need a program code from your employer to be eligible. 看來這不是個免費午餐，得公司買單啊，嘿嘿
