I just now tested these last two ideas and, with a little creativity, I already know they will work really well.
I tested "Recommend" + "Add message"
And I tested just "Add message."
For clarity. In the first test, I added the message to the Recommend. In the second, I added the message to the first post itself. The only drawback for adding a message to Recommend is that you can only add attachments or URLS or things like that. But after that, you can edit the message and add text.
To be honest, from what I saw, "Add message" to the first post works by itself since the first post of a Topic made from split posts will be the Topic post, thus it will always stay on top. And the message (at least in my test) goes above that.
But I like adding some extra stuff with Recommend...
I will play with this over time.
Thank you guys.
