Is twillo avaliable in english?
The user interface of the portal in edu-sharing, that is your workspace, can be changed to english or german with this trick:
Log into twillo. If you want your workspace to be displayed in English, add ?locale=en (or ?locale=de for German) to the end of the URL in your browser. If the URL does already contain a ? anywhere, add &locale=en (or &locale=de) at the end of the URL, instead.
