Be more questions, To the post before my thing where does not gain signature, will not signature be displayed in future either? Made a signature for the first time today. A signature is displayed to the today's post. However, a signature is not displayed to the past old post. Will the signature that did for the first time be displayed today by the past post which a signature did not make if waits for a while in future? In addition, please teach if there was a method to let the past post display a signature.
