There's some great starts in the threads so far. I've really enjoyed seeing what people are doing. I'll be starting in the next few weeks too. And looking forward to it.
I understand the fear people may have showing their wip's or worse not joining in because of what they see, but really this is a challenge for all of us no matter what level we're at. And I think it's good to set ourselves our own challenges and use this as an opportunity as a group work shop/think tank, that will only help promote the software we enjoy using. There's some good open people involved already, and I know you'll get support if you get involved.
All the best everyone.
