I have multiple series here on Tapas, with two I'm focused on now.
I mainly use Twitter in terms of social media.

I do have my own Aurthor Website for all of my book releases that I should update more often.
(Honestly thinking of getting more assets for this very much a WIP)
And finally I have a Patreon and a Ko-Fi page, I'm beginning to advertise these more.
I do have a YouTube Channel to, but I'm switching gears from Let's Playing to do more edit heavy work.
