Please visit either patreon.com/ddnnacheta or buymeacoffee.com/ddnnacheta if you want access to everything about my book, DLMF. I will be using Ko-Fi specifically for sharing sketches and ideas with some Early Access content. My intention is to post updates once per month to reduce spam. Also, please check out my Ko-fi shop. There you can find stock graphics as well as English lesson packages if you need an English tutor.
