I have found this page: https://confluence.atlassian.com/display/JIRAKB/How+to+Customise+the+Login+Gadget
But we have a need to customize the sign-up page. Corporate wants us to provide a link + give a statement about privacy, and the nefarious things we're going to do with their name and e-mail address. Is there a way to customize that screen?
You can edit this file: /atlassian-jira/WEB-INF/classes/com/atlassian/jira/web/action/JiraWebActionSupport.properties Look for properties beginning with 'signup." and edit those. In our case, we needed to edit the signup.desc property. Then restart Jira.
NOTE: you'll probably have to do this every time you upgrade Jira.
I think some custom development would be needed to accomplish this. Are you hosting your own instance? You could edit the template directly (not suggested) or write a plugin that could hook into the desired screen.
I know this is an old discussion, but just in case someone else would need to to this, here are some additional info about how to get it done in JIRA 7:
1. In order to get the changes to /atlassian-jira/WEB-INF/classes/com/atlassian/jira/web/action/JiraWebActionSupport.properties visible on your page you must be using the default language - it is "English (United Kingdom) [default]".
Otherwise you would need some more tweaking... like altering your language package/add-on ( there are some suggestions on that here: https://community.atlassian.com/t5/Jira-questions/Edit-the-sign-up-page/qaq-p/55720 )
2. Indeed, it is not recommended to edit the template directly, but if you really need to add/edit something from the atlassian-jira/views/signup.jsp page (and make it visible) you will find some valuable info here:
As also mentioned above, these changes need to be done again after each JIRA upgrade.
