What are rfcs? read rfc 791 that defines ip, and briefly describe one thing in the rfc that caught your attention? (this is not a trick question, just a way for you to express what you personally found interesting)

to change your username, you must:

1) make sure what the username you want to change to is allowed in this community

2) contact a administrator (for example, jaysl)

3) through pm, tell the admin what you want to change to

4) if the username is allowed, it will be changed in a matter of seconds (minutes at most)
