This is an announcement of a new free web-based viewer for IGC files- you
can find it at http://http://glidingweb.org/IgcWebview/. It was developed
in the UK by Alistair M Green and Richard Brisbourne.

It's designed to work on just about any browser or operating system down to
Android phones- just as long as you have an internet connection.

We'd love to get some feedback, also hear from any javascript/php
developers who might want to get involved (techies note- we're on GitHub).
Preferred contact is the e-mail at the bottom of the help page.

You appear to have accidentally omitted that github link...

A search for 'igcwebview' does not find it.
