The userboxes I made:

A small box with all of them can also be found at User:Cuckooman4/UBX/UBXList

Also, you can see all the pages under this page with Special:Prefixindex. Note that anything in italics is a redirect, meaning it's either an alternate name for a userbox or a redirect to my deleted page. Also, documentations are included, because it only searches for pages that begin with User:Cuckooman4/UBX/, not pages that begin with User:Cuckooman4/UBX/ and don't have a slash after that.
