Here are the tasks I'd like to prioritize in Jan 2016
1. Spread the word! The more people who are aware of the wiki, the more who can contribute
2. Flesh out the investigator bios! Players tend to spend a long time picking their character, especially when you have all expansions, so there are a lot of investigators to choose from. Helping them get familiar with the characters ahead of time helps.
3. Flesh out the Old Ones bios - This really helps cement the mood and experience when you know more about what it is you are up against.
4. Add pictures - self explanatory
5. Add gameplay basics - Turn sequence, description of actions, etc. - To help remind and prepare players
Naturally, if you or anyone else wants to work on anything else, by all means please go ahead.
