It can be usefull, in forums, becasue, if you accidentaly did t put your correct date of birth, have the chance to fix it. And is ShellShcok Live 2 game, the option to show people some dates of you, like your age, your level, your total xp, like in forums but only in game too. What do you think about?
Well, Kyle didn't invent this forum software. You might wanna suggest it on the XenForo forums, although I agree with this. My birthday is supposed to be March 20th. I think this is not needed. Most games don't have these options anyway. You can ask them. You can know their levels if you don't close your eyes.
