How to modify or edit the old post in this forum

Dear All,

Few months ago I created post and asked for suggestion. In that I need to edit the person name or that post to be deleted. I had sent so many emails to the admin but didn't get any response. I tried from this portal, it says that within 24 hours the content to be modified otherwise cant.

Please help me to edit the content to modify the person name to avoid any conflicts within that family.

Thanks,
