Signature after the Entry of a Blog

So, I have a question for all the bloggers...I'm fairly new to blogging, and I've been trying to add a signature to the end of my blogs...as you can see on most of them the "font" probably doesn't look like this to you below, because of most browsers not having the same font I'm using here...This is how I would like it to look, if I knew the way to install it correctly...anyone have any answers as to how to have it how up like this, but without the box around it. I've tried a couple different things...but I'm still not there yet.
