Telling tales - character building (orientating and connection controls)

 For this part of the tutorial I folowed it, not really understanding what I was doing. I created null groups and attatched them to the joints but not entirely sure why. 

One thing I did learn was that you cannot select a null group in the grid, it has to be selected in the outliner

 I got the next section, of parenting up the controls with the next on up in the hierachy, as this was similar to parenting joints, so now for example, when I rotate the elbow contoles, everything below (wrist, hand, fingers) all move too.  

I got to the stage where I was starting to connected the joints and controller, but when I did this, and connected them, the joints flipped on their side, and even though they connected, this isn't how it needs to be.

I asked my peers if they knew where i'd gone wrong, and Malachi said he'd had a similar problem and it was down to parenting the wrong way round. So I now need to go back, watch the tutorial again and try and correct my mistake, if this fail, I'll have to ask for further help.
