FYI - @lauriewayne1 has set up a new slack system for CAN-US ‘support’. We know this is not perfect. But we felt we needed something. It is separate from the OFN-Community slack because we know we need to keep user Q&A stuff off of the main community slack. If any other instance wants to create a support channel on this new support slack - let Laurie know and I’m sure she can send you details.
Second - thanks for all the above responses. I think we should approach this in a stepwise fashion and learn as we go. Frankly, I am reminded about the time 2 years ago when I asked about mutualizing efforts for instance wordpress sites. Choices were for Canada to ‘go on its own’ and get something up quick, or work collaboratively. So - that took 2 years. 
Don’t get me wrong - result is GREAT. But because it took so long, it extended beyond the funder’s deadline and that caused us a budget problem at OFN-CAN. Anyway, in retrospect - I learned that sometimes ‘quick and dirty’ can be good. We don’t have to all move together all the time.
Third - from the above comments - it seems like a fairly simple immediate action would be to have a Support Discourse . At least that is better than slack. I found this dicussion from back in 2015-16 about this. Can anyone update where we are at with this? Is it possible to piggy back on our existing community discourse to do a support discourse for users? @maikel @danielle - you were involved in this at the time ? what do you think @Jen? and @Rachel - this old discussion suggests France was going to use discourse for support - but did you decide not to? why not?
