Offline messages to server group?

[VitaliusDFox]

Is it possible to send offline messages to a group of users?
Example:
Large server. 400~ users in prime time. 2k~ users total.
And I have group of moderators(30~) i can't remember all of them, but i need to be sure that they ALL receive my message. Host message with modal window can do that, but i don't want to bother another users.
so. Is there any way to send a message to user group (even offline members too)?

Hello

By the client, it's currently not possible.
You have to use plugin, tool or external script for that (depend of your permissions)
