Take a look at how it is done for chats.
You can probably use this same code but pass in the text input element of the shoutbox.
I need to alter
account/profile.tpl with a Plugin. Particularly, I'm interested in block with age, email, location.
I want change layout from single panel with centered text on single panel with 2 columns.
Seems NodeBB should be extended for such task, maybe you have some ideas/preferences.
