Why should introductions be required? For one thing we are on the internet and user accounts and names can be created at whim. I could create one tomorrow, restart the F16 weight thread and introduce myself with a fabricated/false story and dupe many users. I think take the post on what it says, and by choosing not to comment usually means the thread dies if you don't want to discuss. Simple really, and less confrontational/antagonistic compared to many of the users on this forum who feel compelled to "die by the sword" for F16.
