In my experience, private instances of PhpBB forums provide niche webtools that are necessary for community building that Reddit could never replace. The Tetris community created a Javascript gui called Fumen (https://harddrop.com/fumen/ https://harddrop.com/fumen/), that can be embedded into PhpBB forums. The chess community created Javascript GUIs that read/write .pgn files (aka: move-history files) to help the community discuss games. The Go community created a similar GUI for Go games. Etc. etc. ----------- Since the administrator controls the whole webpage (including Javascript), you can host local tools in a Reddit-like environment. I think people are sleeping on the potential here, especially if you've never used these custom web-GUIs before.
