As you can see, when you visit someone's forum profile, the URLs show that these forums work on a numerical user ID system represents each account. The actual username of somebody is just a sub-value stored somewhere even if the entire account is tied to someone's overall Verizon account. Needless to say, I think it would be possible for people to change their usernames if they wish since we're all Verizon subscribers and pay to converse here. For me, I need a username change for my own personal privacy, but I've been denied it by the Verizon staff here. I find that somewhat unacceptable and for me, unsafe. Not everyone is going to put a lot of thought into a username for these forums, and it would be a useful feature for all of us.
