Running a forum site is a lot of work :). We can do a google group or something. But then there's another aspect to it, which is staying close to the cause, I don't want reef-pi to be a tech-centric thing. Its focus is to ease reef keeping, and having the discussion here helps with that cause. We have an opportunity to learn the best reef keeping habits and address the most common challenges here by being with the community.
That said, I'll link the important posts in this thread to reef-pi website as a separate blog. I don't think it will be hard to just create dedicated threads and builds, we can group them with #reefpi tag. If the original authors are not interested in it, I'll take permission from them and start those. We can sticky those links in the very first page of this thread. There are a lot of other tricks we can do to address most of the current challenges, here in r2r, where the community lives.
