Looks like you have your rep disabled. You can go in through your User CP/Edit Options and check the box that displays your reputation level. That'll allow you to see the last five or so people who've given you rep. It's just a fun feature of this system so people can give rep to others. You've had several positive reps, enough to add up to 190 points. I'm not sure how many people individually have repped you because different people carry different rep "weights," depending on how much rep they have themselves.

The bottom line is 190 points means you're a very nice guy. Clearly.
