He means "Welcome to PPRuNe"", Joffrey.
You could fly that route as you suggest, but a straight line route takes you N of the Charleroi Class C so unless you've a particular training wish to do the transit you might want to think about keeping clear. LGE is not located on the airfield, so Liege may find it easier if you route through their overhead rather than over the VOR. Norvenich is similar to the comment above for Charleroi, in that routing outside and N of the Class D is more on your direct route than the NOR is.
You may be asked to freecall Liege and Norvenich instead of getting a handover; I wouldn't necessarily expect one.
