有没有一种软件是可以知道对方地址的？

Is there a software to know each other address?

这点可以通过创建一个消息节并使用对方地址和消息对它进行初始化来实现。

To do this, create a message stanza and initialize it with the peer address and a message.

如果有另一个用户将一封邮件发至你先发的那个地址，那么那个人就会获得你发的那封信，你也可以获得他发的那封信。并且，你们两人可以获得对方的邮箱地址。

If another user sends an email to the same address as you, they get your note, and you get theirs, in addition to each receiving the email addresses both of you sent your Invisible note's from.
