More attributes for portal users (e.g. company name, role/group, persona-mapping) Merged

It only seems possible to get a name and email from portal users.  It would be helpful to understand more about our collaborators as we have many customers and within the customers many different stakeholder groups.  They want different things, within and across customers.  Being able to capture more fields from the portal users directly such as company name and role or group would be great.

Internally, if we could map portal users directly, or perhaps through their role/group to our personas, then our ability to connect with the most suitable collaborators on an idea would be great.  

This is not so much about the idea contributor, but those who 'vote' on ideas (needing more than a simple yes/no vote is covered in another idea).  When an idea starts to gain traction internally, connecting our UX folks, design folks, product folks with those who will be the most helpful in ensuring we deliver the best feature possible would be invaluable.
