Gaelic Interfaces

Well, I hate to suggest that Microsoft actually did something right, but they have worked hard to support "minority" languages, such as Irish Gaelic. They've provided some tools, and even updated the interface for local language use. You've always been able to change keyboards, and to type in the ASCII or Unicode codes to get non-standard letters, but being able to change the whole environment to support a foreign language has usually been limited to the "biggies".

Now, though, you can download a completely changed interface for dozens of languages. Using their Windows Language Packs.

I haven't installed any of these tools (they change the entire interface, menus, dialogs, etc, into Irish Gaelic and I'm quite certain that I don't have the vocabulary for that yet!) But, the instructions note you can turn the new interface on and off, so you should be able to go back if it's just too confusing. Maybe I'll try it on my laptop (not quite willing to trust MS messing with my interface on my primary home machine).

Windows XP in Gaeilge
Office XP Proofing tools (including spellchecker). Note that this works with Office XP only, not the latest version. I wasn't able to find anything more recent. Hm. Maybe Microsoft is letting me down.

Firefox also has a Gaeilge interface (although not for the most recent version 3).

There are also some non-MS tools out there for the aspiring Gaelic author, including a windows version of GaelSpell 3, and a Gaelic version of Google.
