Orange? Make that a lime.
Dear Orange, if you try to set up a wifi on a high profile conference like Leweb I would suggest you talk to your technical department first if you are able to do such a thing.
Obviously you are not, you have proven that over the last two days.
You did serve us lime, not orange. Perhaps you should consider a name change.
(Why can I post now? Because only a fourth of the people are left. It seems they could cope with 250 people.)
