Hey folks, welcome to the forums! As you may or may not know, this website was formed, in part, as a response to the concern that using other venues (such as Facebook) to discuss going to the airlines may result in reprisal since other outlets utilize your real name. Thus, choosing to use your real name is entirely a personal decision. That being said, don't use your anonymity for nefarious purposes. Let's make this place an awesome community, not another place where people go only to gripe.
For your intro, share whatever you are willing to share. There are no requirements, though making an intro is highly encouraged so people can see where you're coming from. Welcome!
