Hey Daniel, nach cuir thu seo gu ceann an liosta (sticky), mas e do thoil e?
As I've noticed I keep on posting the same links again and again, I thought a list for reference might be useful.
If you are a beginning learner of Scottish Gaelic, have a look at these sites:
http://www.taic.btinternet.co.uk/ - This is quite a comprehensive online course, rather traditional and grammar based in its approach, and with sound files for all the words and sentences. It is provided by a native Gaelic speaker, as far as I know.
http://www.bbc.co.uk/scotland/alba/fogh ... ndex.shtml - This is another online course, provided by the Gaelic BBC. Compared to TAIC it presents more of a conversational approach, with lots of useful everyday dialogues, including sound files as well.
These two online courses will give you a good start, whether you just want to get a first impression of the language, or whether you can't afford any textbooks yet.
Try out the rest of the BBC site as well. Click on "Èist beò" in the upper right hand corner to get to the online radio programme.
For in-depth information on Gaelic phonology see here http://www.akerbeltz.org/ - this site is a real treasure trove, with very detailed explanations and lots of sound files for all the of the Gaelic language. The site is maintained by a German linguist with expert knowledge on Gaelic.
If you want to get in contact with the Gaelic (learners') online community, have a look at this site: http://www.tirnamblog.com/ - there are lot of people writing blogs in Gaelic, but be careful, lots of them are learners, even mere beginners, so you will see loads of incorrect Gaelic in those blogs
There used to be a nice international Gaelic forum on the web as well, but it's been down for a while.
If you need an online dictionary, the best one is http://smo.uhi.ac.uk/gaidhlig/faclair/sbg/lorg.php - but one of the biggest mistakes you can make as a beginner is typing some stuff in there and translating your ideas word by word into Gaelic. Do try and learn some basics first, and make sure you know a bit about Gaelic sentence structures and some fundamental rules like initial sound mutations, etc.
In case you have any questions, feel free to ask here on the forum.
