Can I draw fanart/write spinoff fic/make podfic/some other sort of transformative work?

As long as you show me!

Translate into another language?

Yeah that too (with credit to the original I guess)

Are you ever going to update/finish [x]?

If it's a fanfiction, then yes, I eventually intend to. Someday. Eventually. When my brain decides to work properly. If I ever decide to fully abandon a work, I'll make a note of it somewhere.

If it's something else… Maybe. Maybe not. Best bet is to yell about whatever theories/ideas it made you have at me which might spark inspiration again.

Where can I yell at you though?

Tumblr is your best bet, but I made a retrospring special for you: https://retrospring.net/@domoz
