Good to hear the knee is feeling better

I'm house sitting at the moment so it's an easier time for me to have a forum break than usual but still now while visiting my mum i manage to end up on the computer which i think is frankly a little sick!

As for answering stuff you know nothing about I'm not sure of what makes you think i know anything about it and i'm talking about it so why not you too?

If you have ideas, comments or just a guess it will all help because i'll have to double check the literature or try something to work out what i think about it and that will teach me more too.

I think it's easy to miss key things because you look at things from one angle so hearing other people's angles on things is always good.
