 # Warnings
+WarningPasswordSetWithNoAccount=A password was set for this member. However, no user account was created. So this password is just an information and may not be used. If you don't need to define any login nor password for a member, you can disable option "Manage a login for each member" from Member module setup. If you need to manage a login but without password, you can keep this field empty to avoid this warning. Note: Email can also be used as a login if the member has a linked user.  
 WarningMandatorySetupNotComplete=Mandatory setup parameters are not yet defined
