Hi,
I created a new page on meta: http://meta.wikimedia.org/wiki/Philip_Greenspun_illustration_project/Get_involved
It lists ways that people can help take part in this project. Most of them are not about creating illustrations! :) There are probably more that I've forgotten right now, too. Please add to the list if you think of them.
There is also a section where you can sign your name if you're interested to help out in some way.
thanks, Brianna
