Hi Alroy,
I hadn't thought much about it. Something like Github would be really nice. But maybe you could just start with a forum that allows attachments.
Are there any existing sites that you (everyone) use to share circuits? If so, what are the features of those sites that you like? How could they be better?
If everyone uses different sites already, maybe we should just have a forum where people can post links to their projects?
What does everyone else think?
