first, be sure it's a working spell, second, proof read it to be sure there's no spelling or grammar mistakes.
you need to join a coven, spell casters is open to anyone and you can post anything. they are trying to fix it up, so please, follow the two rules i posted above before posting. if you choose to join a different coven, you need to be in the council in order to post spells.
to join a coven you go to their profile page, and you should see a spot that says 'apply to coven' click on it, then it should take you to a second page asking if you're sure, then you're in the coven. [or need to be approved depending on how the coven set it up]
