This would be called “Other” and the description would be “For things that just don't fit in the other subforums.”

I believe that was rejected:

9.3 Off-topic or miscellaneous section on the forums
This forum would have been used for posting about anything that was not necessarily related to Scratch. There actually used to be a forum topic like this, but it was difficult to moderate, and so it was shut down and replaced by the “Things I'm Making and Creating” and the “Things I'm Reading and Playing” forums (which do not completely allow off-topic posts).

This suggestion extends to an off-topic or miscellaneous forum for Scratch-related topics. If there is something that you would like to say, Scratch-related or otherwise, and it is not a good fit for one of the existing forums, it would be a good idea to make a project or studio about it instead. This suggestion also extends to the text-based games forums; for more information, see this post.
