Heads up about the Forums shut down


Important Update

We appreciate your participation in these Salesforce Discussion Forums! It’s active members like you that keep our amazing community going strong.

At this time, we want to give you a heads up that on December 4, 2023, the discussion forums will shut down and all relevant discussions will migrate to the Trailblazer Community digital platform. This move brings all conversations around Salesforce development together in one place and provides more opportunities for our broader community to connect and share. We will be removing outdated, obsolete, or spam content and migrating only relevant discussions to the Trailblazer Community digital platform.

Starting November 20, you can view discussions but not post new questions or responses. On December 2, you will no longer be able to access the discussion forums from the Salesforce Developers website.

Please take these steps before November 30, 2023, 11:59 p.m. PT to ensure your contributions follow you to the Trailblazer Community:

1. If you’re not already a member of the Trailblazer Community, sign up for a Trailblazer account using the same login email address associated with your Developer Discussion Forums account. This is crucial.
2. If you already have a Trailblazer account, and it’s using a different email address from the one you used for your Developer Discussion Forums account, we recommend that you log in to the Trailblazer Community and connect your forums email address to your Trailblazer account.

Once you’re in the Trailblazer Community, join the Migration Support Hub users group to help you navigate this transition.

We will keep you up to date throughout the transition, and we look forward to seeing you joining the developer discussions in the Trailblazer Community!

Sincerely,
The Forums Support Team
