Email Notifications From Ideastorm
Right now, if someone posts on your idea, the only way to know is to check by going to this website, logging in, and see if there is a reply. I think an easier way is for ideastorm to email you when someone has posted something on your idea, like many forums.
Status update: We have added email notifications to the site which you can opt into in your profile settings. Thank you for posting your idea!
