Hello @EvaCVM,
I can’t wait for the Blue Moon- it’s a really exciting one! 
Absolutely! There’s currently a discussion thread going where folks are sharing their spells, rituals, and other ideas for the Blue Moon- I hope you don’t mind if I link this thread into that one to prevent a duplicate discussion.

Blessed be and happy Full Blue Moon!
