Hello there!
As you may be aware, we are retiring Special:Forum and migrating all Forum content over to Discussions before migrating your wiki to the Unified Community Platform.
Discussions has recently received a wave of interface improvements to make the feature more comfortable for Forums users, thanks to awesome input from Forums communities and admins.
When your wiki has Forums content migrated, the transfer process will render the Forum into a read-only state. If Discussions hasn’t already been enabled on your wiki, the process will enable it as Forums goes read-only, so you can continue to communicate while the transfer is ongoing.
While Discussions does not support wikitext, we’re using a special converter so that your old Forums posts will look basically the same with the same formatting and templates after they have been migrated, with a few very rare exceptions. Note that editing old Forums posts and comments with wikitext on Discussions will break the formatting.
Additionally, Discussions requires participants to have Fandom accounts. You will not be able to contribute anonymously.
Check this archived thread for some frequently asked questions, but otherwise let us know any questions or comments you may have about this.
