When I share a project using iPlotz option (no mail with url) the person who recive the invitation can not post comment. Do they need to subscribe at least a free account and be logged in? When I create an html preview and send the url via mail they recive the mail and have the possibility to post comment at any time creating an account.
Why this difference? Thanks and regards
Commenting on project is free. There are two ways to add comments to a project. One is in the HTML preview. Another is within the iPlotz application. Please have a look at video tutorial "Preview Mode" in the "Tutorials" page (http://iplotz.com/helpvideo.php).
