Can one of you guys help me here... I am fairly new to this...

Can one of you guys help me here... I am fairly new to this trading, but need to grasp the option. For example with the GRK ops: When you buy them at current price do you then sell them at another date set by the company??? Do you then get the chance to buy them fully out at a certain date??? How is the money made on them compared to a normal share??? And why are they better value than a GDY option?? All this explained in ley terms would be very much appreciated by someone who loves to learn.. Thanks to all those out there that give me a bit of time, will buy you a beer at the Beach Hotel in Byron next time you are here..

Cheers Scmickboy

PS hold 20,000 GRK that I got at 8.0 cents
