well Deeja it's depends on things. if the person's demanding about their 'google search' request, some might not help [you catch more flies with honey than with vinegar] if the person is vague [teach me about herbs] this can also result in a 'no way' from other users as it is a broad topic and we have lives outside of this website. yea, it's annoying to see a mob telling you to 'do your own research' but it's only because that's how we learned, and if you're demanding and arrogant about the request, people are going to treat you as such.
now, regarding the question, there are many ways to cast a circle [circle casting isn't exclusive to Wicca either] bare bones of it, you find the four directions and place four candles in each [east=air, south=fire, west=water, and north=earth for the directions elements] start in the east, feel the energy entering your body, welcome the air element, light the candle, point at the ground, visualize/feel energy going from you into the ground creating a line connecting the air candle to the fire candle. welcome the fire element, light candle, hand down, continue to water candle. repeat for water and earth, then walk around the circle two more times until reaching the east/air candle, then place your hand on the ground to 'ground' the circle. to open the circle, go in the opposite direction, thanking each element and snuffing out the candles.
you can alter the casting, some start in the north, others use rocks instead of candles. whatever works for you. research various castings to find one that works for you.
