We have about 10 years of ideas, comments, and proprietary information in our JIRA. We want to start to allow our community to create JIRAs with their ideas, add comments to existing JIRAs, and vote/watch issues.
How can we open up our JIRA installation without giving any access to our existing information?
For example, should we create a new group (jira-community) and just grant permissions to specific issues to that group? Along with the permission to create, vote, and watch issues?
