Discord is not a substitute for forums, but alas.
Gearbox forums

Gearbox Software announces that they will be shuttering their forums. The process has already started to happen with old sections being converted to read-only a few days ago.

Gearbox notes that users will have about 30 days to save any old posts they want to keep for whatever reason. Later this summer, it is expected that Gearbox Software will launch a new website and when that time comes, the forums will cease to exist.

The plan is to instead let fans and the community shift over to Gearbox's other social media platforms. These include Twitter, Facebook, Instagram, Twitch, and Discord. It seems as though the most obvious place for the community to congregate will be Discord. However, Gearbox seems to run and maintain several different Discord servers for their different franchises. Perhaps more frustrating is the fact that they have a separate Discord for Tiny Tina's Wonderlands instead of including it within their existing Borderlands Discord server.

While Discord is great for all sorts of things, serving as a substitute for forums really isn't one of them.

The full announcement about the forum's closure can be read below.

To our Forum Community,

We’ve had many good years of conversations on the Gearbox Forums. This has been a great place to connect with all of you and a haven for amazing discussions, builds, and support. During the past year, we noticed many of our community members prefer to engage on our other social platforms—and that’s great. We love talking to y’all and keeping the community going there.

Looking at where the conversations are taking place and feedback is expressed, we want to continue that dialog on our social channels where much of the community is getting their information. Our Support team will continue to receive your feedback and concerns through support.gearbox.com.

As of July 19, 2022, we will turn categories to Read-Only. This means members will no longer be able to create posts on the forums, but folks will be able to read previous posts. This will provide 30 days to save any content you want to keep before it is closed. Later this summer, you’ll notice a new Gearbox website and the forums will disappear entirely.

Thank you for years of chats, guides, support, and for making this a great community. We look forward to continuing the conversation with you.

<3
