I might be working on a event website in Drupal 6, nothing fancy except for a registration form that I need some help with.

Form needs to be https if possible and have the following features:

-the form is for an event and needs to be in 3 languages
-users should be able to login and change the information they submitted until a deadline is reached
-ability to add documents
-we need some sort of reporting tool to analyze the entries
-automated email reminders for users that have not completed their forms
-depending on where the users are from (Country), the form shoots them an email with specific per country instructions for passport requirements etc.
-users should be able to see each other’s basic info like name and country, etc but not the additional information they supply.. so maybe the event form and the basic website registration are different forms?

If you think this is possible let me know and I can provide more details, but the text above pretty much sums it up.
