List all document editors

#set($targetDoc = $xwiki.getDocument("Main.WebHome"))
  ## Or any other document. Or just use $doc, the current doc.
#set($editors = $xwiki.search(
  "select distinct rni.author from XWikiRCSNodeInfo rni where rni.id.docId = $targetDoc.id"))
#foreach($editor in $editors)
* $editor
#end

## This works with the current document, $doc, but can be modified as above.
#set($editors = $xwiki.searchDocuments(
  ", XWikiRCSNodeInfo rni where rni.id.docId = $doc.id and rni.author = doc.fullName"))
#foreach($editor in $editors)
  ## Write a link and a proper name, not just the document name. Can also be used in snippet 1.
* $xwiki.getUserName($editor)
