Can you tell me what is involved please?
I have seen it mentioned on here a couple of times but never really looked into it properly. Now I've found out that Dp may have bought me a consultation or whatever it is for Christmas!
I've never mentioned it and it's not something I would expect him to think of so either he's a MNer too or he works with one. 
I have looked it up since and it does look good but what actually is it?
