Description of problem

Hello, I'm currently trying to figure out a way to create my own custom activation emails. I want to be able to put a custom image of the forum's header and a few words from myself in said email that would be sent to users who plan to register. But no matter where I look I can't find the option to create a custom activation email, some help would be appreciated! Thanks in advance!

TL;DR how do I make a custom activation email?

Sorry,it is not possible at this time to custom the activation emails.
