Can GSA make publications on forum topics?

Thanks, I understood how to post messages in the forums, but I have a question about the text we publish, an example: http://prntscr.com/lfcrx6
How can I change my "message subject" and the text I am sending? Where to look for it in GSA? For example, I want this: http: //prntscr.com/lfcvro
Thank you.
