I have several issues with Ubuntu 12.04 and the Unity Desktop, but I will focus here on the missing US English dictionary. And the wrong date format as well.
I thought I had posted on this topic, but perhaps I started one and pitched it before I posted it.
I did a fresh install from a Live CD of 12.04, and if I remember, I didn't have to change anything to have American English and keyboard. I did not find the standard American date format, "May 25, 2012" available. Only the European "25 May 2012" format, or all numbers.
In all applications I have en_GB, with spell checker telling me I am wrong on "color" in favor of "colour" to name one example.
Doing battle with the missing spell check function in Firefox, unless I open up more tabs, I went in and specified en_US, but it is not on my machine because it still uses en_GB for my dictionary.
Now where do I go to retrieve a US English dictionary?
Any advice about the date format would be appreciated also.
