My friends and I are planning to develop a website or app that offers quality and learner-friendly resources. We'd like to know about:

(This is not a formal questionnaire, and responses to any of the following will be appreciated. I do not see 'foreign Chinese learners' as 'English-speaking foreigners', though English is the only foreign language I know and in which this discussion is written)

     ·the books and dictionaries you use (their names) [Do you have many choices? Do you prefer the explanations written in the an English dictonary's way (say Oxford Advance or Merriam-Webster)? Do you wish to have up-to-date usages and examples voted by the natives?...]

     ·the classes you attend (local/online programs)[Are you satisfied with your teachers and the way they're qualified? Do you have clear goals or plans(say to work in China or to get a language certificate)? Are the help of your courses limited?...]

     ·other desirable resources [ Legal Chinese videos with quality bilingual subtitles(audio texts also available)? Links to related websites(say documentaries, university teaching videos, homestay exchange, etc)? Reminders according to the Ebbinghaus curve?  An advice column? Corrections or remarks on your recorded speech?...]

    ·ideas or suggestions for our project (you can simply recommend a similiar website or app)

Thank you in advance for your valuable answers.
