Hi I´m interested to use Community Surveys in my web page. I've some questions to ask before get this extension:

1. Does it supports multilingual surveys ?
2. Can I send private surveys to someone and know who have done it?. I wouldn´t like to create a user in Joomla for each recipient.
3. Can I mix the results obtained from 2 different surveys. All surveys will have the same fields, but each client have an radio element with diferents values (f.e. the surveys will have a radio element named projects, this field values will be different for each client).
4. I have read you can create different URL´s for each recipent. When you send the email with each link, does it stores this relation between  key url - recipent email ?.
5. Can I disable questions from a submited survey without lose the previous recived information?  

Thanks for your help. I hope you can understand my requirements
