No worries Dave, I should have been more clear. Here is the page I was referring to https://kamloopsmakerspace.miraheze.org/wiki/Guilds . Noisebridge in San Francisco uses this model. It is similar to our old room coordinator system in a way. Except it focuses on continuance and is based on focus areas instead of physical areas. It also creates a group of people around a subject rather than one person. This allows continued effort to avoid burnout as well as ensures a continued push if the lead person(s) leaves or gets busy.
For example, Sally says 3d printing is awesome. She gets a few others who agree, and they charter a guild. They get together to improve the 3D printer. They teach a few workshops and do some get-togethers. They communicate under 3D printing on the Forum and document everything on the wiki. Sally gets a job in Vancouver and the group grows apart, we don't have cool 3D printing things happening until Bob joins and says "You should do more 3D printing Workshops" Bob then goes to the Wikki and finds all the documentation about the old workshops and asks on the forum if the 3D printing guild wants to get the band back together. We have cool workshops and get-togethers again. Or Sally leaves and Joe (who is a guild member) takes on the Guild and there is no interruption. The guild would also help new members by documenting things such as printer settings.
This helps avoid "key person syndrome" as well as builds on existing knowledge rather than reinventing the wheel. I think it better reflects the multiple-use nature of our new workspaces. It also allows for higher-level interests. Such as the Meta-Guild on how the guild system would run, as well as a fundraising guild, or community get-together guild. They do not have to be super formal just a few people getting together to meet and work on what they are passionate about.
