Vanilla 3.2 - how to create link to send group message?

  You would need to create your own plugin for that that mimics the MessagesController->add() method. This is why it doesn't work with pure Vanilla:

     public function add($recipient = '', $subject = '') {
  ...
             // Check if valid user name has been passed.
             if ($recipient != '') {
  
               if  (!Gdn::userModel()->getByUsername($recipient)) {
  

  As you can see, what is passed as "authorname" is treated as one user name.

  You must create a plugin that fetches the recipient passed to the add function and transforms it to valid recipients. That would be possible with something like that:

     public function messagesController_render_before($sender, $args) {
         if ($sender->RequestMethod !== 'add') {
             return;
         }
  
         $recipientString = $sender->RequestArgs[0] ?? '';
         // explode by "+"
         // loop through array
         //  getByUsername
         //  add unknown usernamens to form errors
         //  add known users to "To"
  
         // Example for add ing to "To"
         $recipient = implode(['Groucho', 'Chico', 'Harpo'], ',');
  
         $sender->Form->setValue('To', $recipient);
     }
  

  But there is one problem: the add() method still receives the wrong user1+user2+user3 which yields an error. Not sure right now how to solve that. I'm sure there is a solution. If you can't figure it out, just drop a note and I see if I can find a way...

  One could create a plugin with their own form that receives conversation message /subject (and possibly preset recipients) and then send the message internally.

  Just some code snippet:

  $conversationModel = new ConversationModel();
  $conversation = [ 'Format' => 'Text',  
                    'Body' => $formmsg,
                    'Subject' => "some subject ",
                    'InsertUserID' => $User->UserID,
                    'RecipientUserID' => [$recipientID1,$recipientID2] ];
  $conversationID = $conversationModel->save($conversation);
  

  As @R_J noted, to get recipientIDs use Gdn::userModel()->getByUsername() to cycle through user names you get (or prime) on the plugin form.
