Welcome as well. It is always nice to have somebody that appreciates and understands the art Taekwondo. Of course like Oldman said, you will have to put up with a lot of nonsense but if you can filter past this then things can be okay.
I've found in the past that the Taekwondo forum has been a lot of the younger generation coming aboard and some of the questions are ... well you know. You can't blame them for their excitement though.
If I could suggest, don't limit yourself to just this Forum but stop in at Martial Art Talk where all arts are discussed. I think others could benefit from your knowledge ... and you may as well benefit from theirs.
