						Feature 1172 : Email providers exclusion list can be set with CR/LF between each entry. The comma seperator (,) is still mandatory.
						Bug 1175 fixed : Bad translation tag in french language file.
						Improvement of unvalidated users management tab (feature 1174)- Expired users are displayed in red color text.

-- 2.11.4 : Bug 1177 fixed : Width of excluded email providers list reset to ancient value (80 col)
						Bug 1179 fixed : Adding a notice in plugin inline documentation for use of validation groups and status. A default group must be set in Piwigo's groups settings and the "Guest" (or another user) must be set as default for status values.
						Bug 1182 fixed : Language tag missing in confirmation email generation 

-- 2.11.5 : Bug 1195 fixed : Registration displays the good title

*/

/*

 ***** TODO List *****

++ No validation needed for admins users comments (new trigger needed in comments.php)

++ No single email check for admins (new trigger needed in (functions_user.inc.php ?))

++ Password control and enforcement
  -- Empty password (done in Piwigo 2.x)
  ++ Can not be the same as username
  ++ complexity of the password (Numbers+Lettrers+Low and high case+Special+minimal length)
  
++ Security : Blocking brut-force attacks !

++ Opportunity to copy a registered user for new user creation
  ++ new copied user will (or not) belong to the same groups
  ++ new copied user will (or not) get the same status (visitor, admin, webmaster, guest (??))
  ++ new copied user will (or not) get the same properties
  ++ new copied user will (or not) get the same language
  ... and so on
