The person who started a thread should be able to categorize their forum post into a new group if there are no replies. For instance, I posted something in the Spatial Analyst category, but it has no replies. I'm wondering if I should have posted it in the Raster subforum instead. I want to change the subforum group without copying and reposting it since reposting is frowned upon. Or if there is a reply (but not the answer) it would be nice to edit the subforum group without losing the replies.
