Hey there,

I am sorry for the delayed of this reply as it was Labor Day for us.

Issue 1 : Creating a new group message
------------------------------------------------------
Currently we haven't update the latest developer docs yet, it might be some of the part is not explain properly or already outdated.

And I am not sure what is your current requirement yet, is it you just want to allow user to create one of the group conversation button for certain his friends?

If yes, we do have a section to allow user to do that, maybe you can get some ideas how to code it based on your current requirement.

1. Access your logged in user profile then click on the friend tab.
2. You can able to create friend group here (screenshot : http://take.ms/NVjYX)
3. This is the create list form (screenshot : http://take.ms/Lpaiy)
4. When you click that submit button, it will trigger this controller function 'storeList' (JoomlaFolder/components/com_easysocial/controllers/friends.php), then it will retrieve a list of user id then pass into list library 'save' function (JoomlaFolder/administrator/components/com_easysocial/includes/lists/lists.php)

It will store into these following table for this new list.
- #__social_lists
- #__social_lists_maps

Once created new list completely, then you can create group conversation for this list user. (screenshot : http://take.ms/6nJ3P)
This 'data-es-conversations-listid' data attribute will show that active list id.

This is the code render that "Add a conversation" option from that dropdown.

Issue 2 : Renaming of Conversations
-------------------------------------------------
It seems like that is bug, can you try open this file JoomlaFolder/administrator/components/com_easysocial/includes/conversation/conversation.php then find this function name 'getTitle' then replace to this following code :

[gist type="php"]
public function getTitle($initUpper = true, $allLowerCase = false)
{
$title = '';

if ($this->isCreator() && $this->isSingle() && $this->title) {
$title = $this->title;
} elseif (!$this->isCreator() && $this->isSingle() && $this->title_alias) {
$title = $this->title_alias;
} elseif ($this->isMultiple() && !$this->title) {
// the title basically are the participants names
$names = $this->getParticipants(null);
$title = ES::string()->namesToStream($names, false, 3);
} else {
// since the group conversation always save the participants name
// so we can just render the title name directly
$title = $this->title;
}

if ($allLowerCase) {
$title = JString::strtolower($title);
}

return $title;
}
[/gist]

After that, try update the group conversation title and see whether can work correctly now.

Yes, currently we do not have an API to create conversation title.

It looks like this response resolved my two issues. I now can modify group message titles as well as create a group message from a link to specific users.

Is it possible to create a title or subject for a message from within the link?

something like: data-es-conversations-title="My Message Title"

To be frank with you, currently our REST API isn't extensive yet as right now, so that is not possible to achieve this.
