Yeah. I think it would be really cool, the only thing is that we'd need a lot of committed people to pull off such a thing. The 'Shroom started small at first so a WiKirby newsletter doesn't have to be very big.
I should mention that I did indeed talk about it in staff chat, and the staff was generally in support as long as we can assemble a team. Might be able to get a community poll started to gauge interest.
