Welcome Herr Faustnik! Don't worry about the TBI, as most of us have at least some amount of damage either from drugs or alcohol or some other youthful indiscretion.
Not only are you welcome, you are more than likely to fit right in. The best part is that we will not treat you any different from anyone else, as a matter of fact we will break your balls just like we do every one else.
We will also love you like every one else.
You'll just have to get used to it............
