The board is always happy for people to reach them with things that need to be discussed. Because of this we encourage everybody to add items they find important to the next meeting agenda. To make this easy, we have created the following Wiki page, where you can add your items: https://en.opensuse.org/openSUSE_talk:Board_meetings. You can of course also reach the board privately via email email@example.com with your topics if your prefer.
In the next meeting (19-6-2018) we will make a retrospective of the last openSUSE conference (what was good, what was not that good, what things need to be improved for next year, etc.) I you have anything to say regarding this topic please let us know. ;)
