There should be a category for community builds & packages, like the "Community Releases / Announcements" at the Openwrt forum.
People could discuss there the either their firmware builds for a router (like the wrt1900ac and wndr3700 firmware threads at the Openwrt forum) or recent/new packages (like e.g. adblock).
I am not sure what is the optimal name for the category, but maybe either "Community Releases" or "Community Builds & Packages"
Thanks, I tested it by copying my WNDR3700 build intro here. While doing that I noticed that Discourse apparently has less bullet/numbered list formatting options compared to the old forum
Or then I am not yet skillful enough to use all formatting options (e.g. sub-bullets inside numbered lists)
