Thanks for all your help!

As for my real name, I must apologize. I know it's bad etiquette, but I am
required to wait for a few more years (at least until I'm out of the house,
if not 18) by my parents. I personally don't see a problem with it, but I
don't feel it's inappropriate for them to ask that of me. Again, my
apologies.

Once more, thank you all for your recommendations and examples. They're
quite helpful!
