One shuttle bus, one taxi, one plane, one coach, another taxi and I'm finally hooooooome 
@Mini - thank you for your posts, they've definitely given me food for thought (see what I did there?) - will read articles tomorrow when brain is less fluffy.
@liger - if he'd picked me I would have said (I know, because I wrote it down ):
I'm here for Mumsnet, and on behalf of mothers everywhere, to say it is unacceptable that over 3 million of our children die from malnutrition each year. You know in your heart that you could do more to stop this from happening. So my question to you is - what MORE can you do to support women in developing countries to feed their children, and WHEN will you do it?
Thanks for all the well dones - it really truly was an honour to represent you lot.
@scarecrow - your post has me chuffed to bits 
Soooo. Final thoughts are that the G8 did not deliver everything that the IF Campaign hoped it would, but it was definitely a step forward.
Tax dodging in particular won't be swept under the carpet anymore - the public are onto it and it's only a matter of time before public pressure forces more gvt action.
The official IF response to the G8 declaration is here
I really need to go to bed now but just before I do:
Highs: meeting the other amazing IF@G8 bloggers; getting an article in the Huff
; meeting Jon Snow and him agreeing to a MN webchat; lego police vans; Guinness (yum); the Cameron press conference (even thought he didn't pick me); and spending two whole days MNing guilt free 
Lows: freezing shower; scalding shower; coffee at Killyhevlin hotel. That's it - the rest was BRILLIANT.
Thank you so much for sending me - I loved every second. Now I need to go and sniff my children's heads and go to sleep.
:)
