List of e-mail addresses of MEPs	Roman Luštrik	06 marec 2016	html_document

The following script will try to scape a list of MEPs for their e-mails found at this address. This is the result, with an e-mail friendy version which can be found here. Source code can be found here.

For this method to work, in addition to what is loaded in the script below, you will need to have PhantomJS installed and in your PATH or somehow visible to the system() call.

This list was scraped in March 2016 and the file is available in the repository <> Code. If you need to update it, feel free to scrape it again.

NOTE: Some members do not have an email listed and others have more than one, which is why there are more than 751 contacts.

Special thanks to m0nhawk and Jaap for tips on webscraping.
