"PLease change the code of registration to make the Nickname something else besides the Username. Currently the username is being set as Nickname which means the usernames can easily be found by anyone that wants to tag someone. If you tag someone with @... then the nickname shows which is also the username. I would like and I know there are many others that wants the nickname to be something other than the username. For instance be the First name and Last name. So please add the option to set the default nickname either username or ""first name last name"""
