I am not sure if anything related to the meaning of draconity makes sense in an interbal newsletter newsletter (now, if you aim your newletter for people outside the site, it's a different matter, but I suppose you doon't aim it to be that?). The forum is primarily about draconity and everyone can promote their views equally.
Now, traditionally, a newsletter would normally be a letter from the staff to the members regarding what's going on with the site. The points can comprise maintenance and technical issues, changes of staff, planned events, summaries of organized events and whether they were considered successful, numbers and statistics, new systems put in place and decisions regarding everyone and in some cases point of view from the staff regarding important problems or important ameliorations.
It can also include thanks to people who have contributed to various accomplishments.
Really, anything that the staff has to say to the members
