Woah... actual touchpad player? This is beyond myth! I've seen too much, now I can die in peace. Jokes aside, get a mouse at the very least. Playing with a touchpad is worst decision one could come up with during his/her early days. Unless you're a pro and wants some fun and giggles, I strongly advise you to get a mouse. It's cheap, you can get one in the nearest department store (or thrift shop for the cheap-ass one)
And welcome to the community, glad to have you onboard.
