Welcome x567,
Just to refresh the PPRuNe rules, commonly, we're not eager about promoting other websites in posts here. Sometimes we lighten up a little, but please do let's bear this in mind. As this thread does cross lines by its very nature, a lighter touch is okay, but generally, please avoid promoting other sites in posts here. Of course we understand that our members visit other aviation forums too, no problem at all, and members are welcome to continue to grow the PPRuNe forums as well.
