List all the users that have created at least one page in the wiki

Description

Code

More efficient, but requires programming rights

#set ($list = $xwiki.search("select distinct doc.author from XWikiDocument as doc where doc.author != ''", 0, 0))
#foreach ($item in $list)
 * $xwiki.getLocalUserName($item)
#end

A bit slower, doesn't list global users in virtual wikis, but doesn't require programming rights

#set ($list = $xwiki.searchDocuments("where exists (from XWikiDocument doc2 where doc2.author = doc.fullName and doc2.fullName <> doc.fullName)", 0, 0))
#foreach ($item in $list)
 * $xwiki.getLocalUserName($item)
#end

Example
