I’m very sad to see this change happen and I think Roblox is losing a great source of engagement by doing this. Had the forum not existed when I joined Roblox I likely would have never progressed past playing games and certainly wouldn’t still be active 9 years later. Groups don’t replace the center of discussion that the forums created where users could feel connected to the Roblox community as a whole. The bug reports, scripting helpers and building helpers sections also provided value that will be hard to replace with groups.
It’s also very sad to see that Roblox will not be hosting archives of the old forums, there is some amazing history there that will be lost forever. I really enjoy looking back at old posts to see how Roblox was in previous years. Old posts from notable users and from the first Roblox employees as they figured things out and communicated directly with the community are fascinating to look at and very much a part of the story of Roblox.
