Hey, you posted on my work
[link] asking how to submit literature.
On the top right of your page it should say submit. If you just click on that it should take you straight to the submission page. If you get the drop-down menu, select "Submit Art" and it will take you to the same page. Once there, there should be two buttons underneath the box next to "Which File". Click the one that says "Add Text" and that should allow you to enter your literature.
There's an button underneath where you type in the Deviation Title, click on this and select literature on the side and choose the option in the proceeding boxes which best suit your piece then submit
Hope it goes well, message me if you need anything else
Most importantly, welcome to dA and enjoy!
