Followed you! My tumblr's not entirely Harry Potter though... Probably only 1/3 HP, with 1/3 Captain America/MCU, and the last third whatever strikes my fancy or makes me laugh or whatever new political fuckery has me outraged this week. Welcome to tumblr! I found it helplessly overwhelming and confusing at first too, and it took me a while to really get comfortable with it. Dicta's post is a good place to start, though!
