You'll need more than just read only access to Jira, (issue tracker), Confluence (this site), and Bitbucket (Source control). You are welcome to join and leave at your leisure. The only requirement is that I need a valid email address for you so I can give your account Write permissions. With that set, you'll be able to:
Comment on pages here at this site
Comment on issues in Jira
Create new issues in Jira
and much more.
Just send an email with the subject Account Request somewhere in the subject line and I'll enable your account right away.
Thanks for your interest!
