I'm a little confused as to the difference between the green blobs and the rep no. I've had a about 3 or 4 reps, but the number is still on 0. Did those reps go towards the green blobs, or were they gained by the number of my posts? If the reps that you receive don't go towards your rep no., then how does the rep no. move up?

Am going to learn and remember how to give them now as been a bit slacking as it's all a bit new to me!

Edit: Just tried to add give rep to someone and I can't seem to do it. By 'scales', is that the green blobs? If not, then what? Or do you have to be a respected member to be able to give rep etc?
