Welcome to the site. If you haven't done so, I'd recommend checking out the Newbie Central to get an idea how things are here and have some questions answered. Also, yes you can post spells in the forums, but look at the different types of forums to see where to place your spell. In order to add spells to the spell index, then you have to join a coven (click on the 'Groups' tab to check out the covens) and work your way to become a council in the coven. You can join the Spell Caster's coven to automatically become a council and you will be able to add spells and articles. Hope this helped, and welcome again.
