C5 Royal and Guards Unit Chat

In the patch notes we can see that members of royal and guards units can use main clan and ally chat together with the main clan.
But the following is unclear. Do the members of a Royal or Guard unit have a speratate Unit chat, only for their use? Or the only way to comunicate between Unit members is to use the Main Clan chat. Someone have tried this out?

i tryed on pts

i did not found a separate chat window for the other unites.

Mystril, can we have offical information on it?

There is not a new/separate chat channel for the clan sub-units. I hope that answers the question. :)

thats a real shame i hope it may come in the future!

so what rights do the sub-clan admins get?
