How do you get a picture of your car with the year and make into the bottom of your posts? I see at the bottom of most of the people who post regularly there is a line, then they have what I guess could be called a tag line? with pictures or quotes. Is this made in your profile? Cuz I didn't find anything there. I wouldn't think this is done with every post.

Found it. I was going to my account. Found it when you click on Private messages

Up towards the top of your screen there should be a navigation bar. Click on "User CP". Under "Settings and options" there is an option for "Edit Signature". That will allow you to edit your "signature line" for all forum posts. You can see mine down below with cars listed.
