I love the latest Byobu update, now no one can post under the tag private if there is not a different recipient from the sender; this is better than before but will be useful for admin be able to post here without be forced to have a different sender.
In my case I want set a sticky post that will be visible to any member that will visit the private message section.
This discussion has some rules and the alert messages can be monitored by moderators.
Before the update anyone can post on private discussion without send the message to a specific member.
Now no one can post in private discussion if there is no a specific recipient but admin should have a possibility to do this to set a sticky topic with important notice, visible to anyone that visit the private message section.
