First off. I would not call it a "janitors project" since that may offend some. A second problem is your notion that documentation is "not-quite-as-important" a task as writing code. I'm think many would say you have that backwards. There is nothing more effective in evolving FreeSwitch than good documentation which helps further development and is an important part of "customer service." Good customer service is then a part of "sales and marketing." Much more often than not, It's sales and marketing that is more important to making something a "real product"  than engineering. "Build it and they will come" almost never works.

Anyway, I think you need a new name for this project.
