there are articles on this site to help you with this, but people normally have two elements, the one they're born under and the one they feel closest to.
off the site, this might help http://www.wicca.in/the-wiccan-elements/
on the site, http://www.spellsofmagic.com/coven_ritual.html?ritual=159&coven=108
the second one can help you try and understand your element better, where the first explains them all. if you want further research, look for yourself. one more thing, if your elements air [or you feel it is] the air element would probably be the best coven to look into first. i was a member for a while, nice coven.
