I need to resolve the rapid please .........

I need to be a way of a letter sent to the participants ... The announcement of their news or something

Try a script that uses a :foreach loop that runs against your user database, that calls for the /tool/e-mail script to send whatever it is you want to send.

Of course it will mean that every User entry in your database will need an E-mail address in it, and probably names too, and any other variables you'd like to send.

sorry, but I don't think this question is related to RouterOS. spamming users is not the task of a router.
