It would be very good if you will make possibility to show one or group of questions from QuestionBank to users after they open web site. They will answer a question, will see correct answer and after this window is closing. Of course it is necessary possibility to skip this window. I very need this option on my site.
Sorry for my English

What you think about and what possibility to make this feature?

After you change labels you should save the language file and select appropriate language as default. This is necessary for changes to take effect and this can be done on languages page by selecting appropriate language radio button and clicking "Default" icon.

Here is also help file for ARI Quiz component.
