If you would like to start translating straight away it could not be easier, all you need is a Launchpad Account, and simply fill Irish words in beside their English counterparts. If you do not know a word, you can skip it or if you are unsure, you can have your translation reviewed by another contributor. To start, see: https://launchpad.net/ubuntu/gutsy/+lang/ga
Old translations for Ubuntu can be re-used in Gutsy and rolled out as updates. All contributions are very welcome, and your support means Ubuntu can break into sectors where it is chronically underused in Ireland, such as Government and Education (most of which still require some level of Irish).
Go Raibh Mile Maith Agat!
