How to stick your tagline to all articles?

Hello all,

Hope everything is well.

I was just wondering if there is a way that I can keep my tagline or my signature at the end of each article without having to re-enter it?

For example: My tagline is usally “Be sure to follow me on Twitter @ChiGolfRadio”.

But I have to keep re-entering it after every article.

So is there a way I can stick it so I don’t have to type it again?

Thanks so much and I hope to hear form you soon!

Colin
