Text Messaging on Z10 with "Me" As the Sender?

Hi
When you send a text on the Z10 is there anyplace to change the "Me" that appears to your own personal name as you were on older BB devices? Also is there a setting someone can share where you do not see little boxes with check marks next to them when you send a text? How do most people configure their settings for text messages? If you can post some screen shots, that would be great!

I am on the Verizon stock, latest OS 10.1.0.2039 and do not want to install any leaks until the official

Thanks for your assistance everyone
