Used Olivia from a terminal in Dole Tavaux (LFGJ) yesterday. Filed my flight plan to come back to the UK on line. While I was doing that, the locals mentioned that it often doesn't work and that they tend to fall back on the old fax as mentioned above.
My flight plan did come through and when it works I think it is a well designed system.
I like the notams with their abreviated offering so that you can tick the relevant ones.
