is there any way to get the same prompt for foreign languages into English on the mobile version of the site as you can for the desktop version?
Do you mean a translation feature? (CHYOA doesn't have a translation feature. Browsers might offer that and I guess there might be mobile browsers that are capable of doing that as well.)
Yes,something similar to that because on my desktop I’m given a prompt if I want to translate a given language to English but on my iPod touch I don’t have that
What browser are you using on your mobile? If it doesn't have a built-in translation feature, you may be able to install one yourself.
