In This thread I've 'answered' my own question but i'm thinking that perhaps I shouldn't have done this? Would it have been better to instead add the info from my answer into the question instead? Currently its my only solution for this issue (although it hasn't been very long since I posted the question as dpollit pointed out).
Is there a 'rule' around when you can answer your own questions?
If the consensus is that my answer in the thread is in the wrong place I'm happy to move it.
