Hi Boba and welcome to the forums. Your Dad gave us the heads up so there's no issues with your application.
We've already explained this to the old man and it pretty goes without saying that everyone here, for the moment at least, is far older than you. I'm not about to say young adults don't know any naughty words or are oblivious to the world's vices, but I do have to tell you that sometimes conversation and behaviour in dl can devolve into 'pub talk'. Your maturity will be measured on your ability to communicate and behave within the limits of our one simple rule for all members:
Don't be a dickhead.
I'm sure you'll be fine though :)
Welcome to digital legion, and I look forward to flying with you in alpha 2.6!
