Organize NPC's , probably by campaing, with a general section as well.
Fill in timeline and consolidate various versions into one. But keep it simple, Timeline is not the place for adventure logs, althouh it can link to them.
Write ups while we might possibly still remember for some of the iconic moments in our games. Marked for Death, "I want magical powers", etc.
New updated world Map as well as maybe some maps were missing. Tyr, Feltrest, etc.
Organizing Stuff in Kayliss section.
Logo? - for now none as it prints on every page.
More Character/NPC's pictures.
Groups, create detail pages for those we know more about.
Places- Be nice to have either maps of each individual place. Even if just an outline that can be printed and filled in if needed (example). Also it would be nice to have for most places, zooms of the world map with the location highlighed. So if you don't know where it is you can quickly check the map and get it in persepctive.
Maps - rough global map, giving general areas for main continent, Oceans, Zachar, Northlands, Sahud, Suel, etc.
For anyone who has GM or adventure notes from past adventures, make sure Places, NPCs, etc get added to the appropriate place.
