I teach computing at Sabhal Mór Ostaig, a Gaelic-medium college on the island of Skye, and I am the author of the majority of the college website (www.smo.uhi.ac.uk), and in particular of three major "directory" pages:
Scottish Gaelic - http://www.smo.uhi.ac.uk/gaidhlig/gaidhlig.html
Irish Gaelic - http://www.smo.uhi.ac.uk/gaeilge/gaeilge.html
European minority languages - http://www.smo.uhi.ac.uk/saoghal/mion-chanain/en/
I have put several Gaelic dictionaries on the Internet - http://www.smo.uhi.ac.uk/gaidhlig/faclair/
