I like the idea of the first name feature being applied here.
With professional mod developers or other members who work for companies that develop features for Dolphin it shows clients a great deal of who they realy are.
There shouldn't be a issue with having your first name displayed as there are thousands of people in the world with the same name.
We create profiles to show people who we realy are...it's just personal information such as address, phone number etc. that shouldn't be displayed see more (I know it's not, but you know).
