Enhance the communication of my moderators

[symptome]

I've got the problem, that my moderators aren't informed, what the others did.
Especially when supermoderators do something that a moderator needs to know.

If one moderator wrote a private message to a member to inform about someting (rules...) then he has to post this to the other moderators in our private are (only for mods).

This is double work. And if he forgets to post it, then possibly other moderators do the same and write private messages to the same member.

So I need something that supports the communication of my moderators without extra work.

Do you know something?

Thanks a lot!
