Hey there! Yes I think it's going to be really fun! I've been wanting to make some new fandom friends, so this is perfect :D

I didn't know it's on Tumblr! That's awesome that it's available on different platforms! And yeah, Tumblr's pretty different from journals tbh, but it's fun once you figure it out. I'd also def recommend checking out the Fantastic Beasts tag on AO3! There's a lot of good stuff there!
