Thread:Project:Support desk/Formatting Toolbar

I noticed when I asked a question on this page, there is an "Advanced" link that shows some formatting tools. Is this something I can add to my Wiki (v1.24) for editing regular pages? If so, how? I used to have wikEd, but it disappeared when I upgraded from 1.18 to 1.24. I haven't looked into adding it back yet (assuming it's still supported).
