A very good start.
I'm not sure about your focus — in that it doesn't seem focused enough. In other words: it might be too much. When I suggested that you take on the Composition FAQ or Literary Terms, I was trying to suggest a project that would not be too overwhelming. Here, I'm not sure if you intend to write a guidebook or a reference manual or something in between.
Please see the instructions again. I ask for each individual to have a single entry. This proposal looks like each is responsible for more than that. Why take on extra work?
For the small group: why not just have a more complex term that you work on together? Again, your proposal does not make it clear (or overcomplicates?) what you intend to do for this requirement.
Like I said: a good start, but I think you need to revise and refocus just a bit.
