I've been regularly checking back at openoffice.org for version 3.0. Basically the website says it's an en-us version. I'd been waiting for an english uk version.
I was doing some searching today to find out when that would come out and discovered that if you have a uk intel chip it automatically converts it from your pc settings.
Suffice to say, it's been downloaded and looks great. Much improvement on v2.x which itself was pretty handy :-)
You can download from here.
