Eran, first off, great plugin! I've used it a few times on some of my sites.
Second, When submitting each event, before inserting it into the database, the "link" field needs to be checked for whether it begins with http:// and if not, it needs to be added. Without the http:// at the beginning, the front end of the site will link to http://www.mysite.com/www.link.com, which will be a 404 error on the site.
Also, just throwing it out there even though I saw you post on another thread that you had no plans of adding it, but incorporating the WordPress WYSIWYG editor (wp_editor()) would be amazing! I have a lot of people that would like to be able to style the text and add images into the description of the event, so that would be VERY beneficial! :)
