There doesn't appear to be an English version, only American.  Am I missing something or can I contribute to correcting this?

Hi Leigh,

Thank you for sharing your idea.

This is interesting: Me as a Germany German, I would not even consider doing an Austrian German or Swiss German translation.

Do you see any advantage if we would use GB-EN instead of US-EN?

Background why US-EN is used: US-EN is THE NATIVE COMPUTER LANGUAGE, it is used on most of all computers world wide. Correct me if I am wrong.

What would be the goal for you to do a GB-EN version? Is it worth the effort? Do you not understand certain words in the US-EN or are there technical issues you came across? It would be interesting to see what is driving you to offer your help.

Thank you Adam
