We use V1 Ideas for our own customers and internal staff to log ideas for the software we develop. It's proving very popular and a great forum for user collaboration.

It would be useful for users to know more about who is suggesting the idea. This could be done by having an editable username field and/or company field or even an alias that users could edit to whatever they want it to be.

This will really help when users are collaborating with each other since they will have a better understanding of who it is they are engaging with.
