po-ta-to no 'e'
one piece of advice to give to a newbie, eh? i think it would be magic shouldn't be the reason you practice. if it is [because some people are here only to cast] walk before you run. learn how energy works, and do various forms of low magic before tackling the more powerful forms. meditate, and get a feel for the energy around you.
one more thing [though this is a pet peeve not something pertaining to paganism] set up your profile with a little biography and a profile picture.
