I want to create a global action that is a way for staff to Chatter a simple weekly update about what they've been working on and what they're going to work on next week. Basically, all I want is to have a chatter publisher window pre-filled with some template text:
What did you do?
What are you going to do?
If I create a global action, I made a VF form and generate a Chatter post with the update text, but I lose the ability to create @mentions, which are really helpful in updates.
The simplest thing would be to generate a standard chatter publisher and pre-fill it with text, then let the user start modifying. I don't think there is any way to do that on the platform. I suspect the best thing I could do is create a Google Chrome extension that allows the user to pre-fill the publisher on the client, but that's less than ideal.
Any suggestions for how I might give the user some text in the publisher so they're not starting from scratch and don't lose all the good stuff of the standard Chatter publisher?
