Greetings from Mexico.
When I try to look at some of the pages on the Wolfram web site, like this one:
http://www.wolfram.com/language/fast-introduction-for-programmers/
it switches automatically from English to Spanish, without asking me 1st, like many websites do these days.
On some of the Wolfram pages one can find an option to switch back to English, in tiny print at the bottom of the page, but on other pages, like the one above, there isn't.
Is there a way to prevent this from happening?
