I have very fond memories of PHPBB. A lot of tech communities migrated to Discord now, so that chat history is not indexable by search engines, which makes finding information a little tough. When building Uproar chat, to combat that "lost information" that is inherent to chats, we added a pin-to-feed feature so you can pin anything you said in chat to a publicly viewable feed, which is indexable by search. It's not as nostalgic or "great" as PHPBB was, but it's better than nothing.
