Hi - If you try adding a bunch of trips to the itineraries section the flood control is a bit too aggressive I've just added my last 3 return trips and on all of the last 5 I tripped over the flood control which seems to be set to 60 seconds. I'm guessing that's site wide rather than per forum but if you felt able to turn it down to (say) 30 seconds it would make adding itineraries much easier! I guess most people add at least two at the same time.
