Proposed changes to the EA Wiki page on forecasting [Google doc]

I'm a big believer in the EA wiki
I wanted to give details for people in forecasting for new people/non-forecasters to contact (eg make our community more legible)
The current process for large changes seems to be that we write them in google docs
Let me know what you think of these changes and add any changes you'd like, then I'll implement them all in one go
