The foregoing should read: "Expect surprises".
(joke)
In fact, the projected surprises may occur that the newly created posts half registered users may experience a slight delay (10 min) with the mapping of embedded images. The reason for the delay is that the files on both servers is synchronized every 10 minutes. So do not worry if the newly created someone messages you do not see embedded images. Within a maximum of 10 minutes, they will appear and you.
