IF this is not the project a newcomer would want to dive into, what is then a good, modern Rails app you can learn from? It appears most popular Ruby repositories on GitHub, for example, are tools rather than full web apps that can be used for learning purposes.
A more specific question would be a reference implementation of client-side MVC with Rails backend.

From what I understand, you always had an US account in all the countries you were living. My wife had an US account when we moved to Australia, and it was not possible to access all the content purchased with that account. We confirmed the blocking had to do with the IP address by connecting temporarily through US-based proxies.
It was very difficult to change the US account to be Australia-based. Once this happened we had to re-purchase some apps, but in the end it worked.
My point being that yes: you do find issues when changing the region your Apple account is associated with.
It is not a problem exclusive to Apple. Microsoft, Amazon, Yahoo, Google, all of them fail in one way or another.

Wikipedia is available in 275 languages, and the current logo at least acknowledges that there are other writing systems and that this is not just an English encyclopaedia.
Changing it for a W is a complete disregard of the significance of Wikipedia as a multilingual reference work.
