I'm a novice.
v.0.3.1
Is it possible to create global email template :
has an image at the top and a standard form signature at the bottom?
Where do I make changes?
Not that I know of, but it would be a really cool plugin!
I.e. need to make a plugin (not skin) such as
...
$this->add_hook('message_compose', array($this, 'make_brandbook'));
...
I understand correctly?
Yes it wound need to be done using a plugin, not editing skin files.
