I inherited an old, heavily customized JIRA instance and I'm not entirely sure what's going on at all times. I have some users that think they should be added as a watcher if they attach a file. Is this something that's supposed to happen by default? Does it sound like something a known customization can handle (I don't see any attachment workflows)? Or is there a plugin to handle this?
I'm also curious in knowing how/where to look this stuff up. If there's some admin page that I should have searched for, etc.
Thanks!
