The issue collector allows you to easily embed a Jira feedback form into your own website. This form is typically accessed by clicking a 'trigger' tab exposed along the edge of pages in your website.
When used by people visiting your website click this trigger tab and submit the resulting Jira feedback form, an issue is conveniently created in Jira.
Visitors to your website do not require a user account in Jira to use the Jira feedback form.
