welcome to the site Gwins, i would take a trip to newbie central if i was you =) it is a great help to those new in magicks, asfor simple spells, try learning your basics first. I'll provide links below. Also being in spellcasters coven isn't a very good idea.
1) there is no priest/ess and you will learn nothing
2) most of the spells submitted to spellcasters are by anyone and everyone, they are not monitored by the priest/ess of the coven because there isn't one.
If you really want to learn something, i would browse through the covens on this site, i'd strongly recommend a few:
the Path of the Shaman
Guild of mages
there are also others like Dragon magick that are really good and focus on specific parts of the craft.
also the site moderators are pretty knowledgeable so i would talk to some of them, and ask for help.
There are other really good articles so browse the forums =)
i hope this helps you
