Idea is via me by email. The "issue" we had was the person who set it up, in trial mode added some ideas, many associated to me just via my email address, as I wasn't an actual user yet (screenshot attached). Then we signed up for Aha! and now, to me, these ideas don't really have an owner. Would be nice if there was at least a way, to move stuff like this into an actual user. I am signed up to the app with this email, but they really aren't "mine" =)
This feature has been shipped so that it should associate the actual user to the idea (based on the email address that you had submitted the idea).
We've also recently launched a feature which allows you to change the idea submitter. You can access this by clicking on the "Creator" field for the idea.
You won't be notified about changes to this idea.
