#### 6.8.3 Sending or Not Sending

Well, assuming you've read all of the above, here are two final notes on mail sending with `nndiary`:

- `nndiary` is a real mail back end. You really send real diary messsages for real. This means for instance that you can give appointments to anybody (provided they use Gnus and `nndiary`) by sending the diary message to them as well.
- However, since `nndiary` also has a `request-post` method, you can also use `C-u a` instead of `C-u m` on a diary group and the message won't actually be sent; just stored locally in the group. This comes in very handy for private appointments.
