Chatting with Tencent insiders, I found that he has begun to use an Email account (Figure 1, 2) to log in to TM, which is exactly the same as the MSN account login. The author uses TM2006 Spring edition, can clearly see each other use TM is no longer a number, but an Email account, and from the screenshot clearly can see MSN avatar, some time ago rumors Tencent TM and MSN interoperability authenticity is greater.
Sounds like a fairy tale!
