Searches and public lists can be shared with any of your colleagues also with an Entelo account. Simply copy and paste the URL in an email or chat application and they'll be able to access it from that link.
When creating a list (instructions here), your list will be public unless you chose to make it private. You can change your private list to a public list by clicking the edit button at the top of the list page.
Take the list of private (if box is checked list is private, unchecked is public) and click save. You will then be able to share your list by copying and pasting the URL as above.
