The Austrian Philatelic Society web site is at www.austrianphilately.com, where you'll find details of the society's activities and publications, as well a lot of general information on Austrian Philately.
This site has nothing to do with the town of Kitzbühel in the Tirol, although the Webmaster has spent many enjoyable summer holidays there. Their official website will give you more information on the town, and has links to the tourist organisations.
Trams!. Much of this information is quite old - some is last Millennium - but it's a factual record, eg this tram was at that place on that date. So while it may be uninteresting it isn't actually wrong!
