Click on your Private Messages, then go to Edit Signature. On the left, under settings and options.

Yup, as JPD just mentioned above, the text that is inserted under the bottom of all posts is called a signature. If you'd like to insert and/or edit your signature, you can do so here.

Hope this helps.

Cheers,
