On My Account > Hubs (or Stats), you can change the sort order by clicking the title of the column. So you can sort by score (the default setting), by title (alphabetically), by date published, etc. If you click on the same title a second time, it reverses the order (for example, starting the alphabetical list with Z instead of A).
You can also change the actual Category of a Hub, so that they might possibly show up differently on your profile page.
