I noticed that you are working on adding statistics content to WE. I've also been working on statistics. We have that in common :).
A few months ago I started a math community, at WikiEducator:Mathematics Community. (But then I got too busy to promote it.) I'm suggesting that we maintain a list of people who are interested in math. Please add your name. This will be a good place for us to discuss issues related to math, e.g., in the discussion tab at the math community page.
I've also created the page Portal:Mathematics as an organizer for our work in mathematics.
And as we get larger, maybe we'll want to break off into a Statistics community--something to look forward to.
Hope to see you there soon.
