1. Exporting - we have an option in the core of JEvents to export all events in iCal format for importing into calendar apps and other online calendars like google calendar etc. There are tools available online to convert iCal files to CSV.

2. We use the normal Joomla email cloaking script to email addresses are hidden from search engines. Additionally you could use the silver member custom fields addon to capture these fields and control the access level so that only logged in users can see this information

3. The standard images/files addon (silver member) allows you to upload images or files to events including PDFs - again you can set the access on this so that only logged in users can access the flyer.
