The idea of our users submitting, voting for and commenting on other users Ideas is a powerful one. However, as our clients tend to be rather secretive (being investment banks and hedge funds), I am doubtful we would get any uptake. To encourage this, it would be great if non-internal user names were obscured fror everyone other than internal users.
Today we launched a new option to hide portal user names in ideas portals. With this setting enabled, users can add, vote, and comment on ideas anonymously within the portal. Check out the blog post for more details.
