I had a lot of repeating questions too. Sometimes I go back to previous newcomer page and just copy part or whole answer to question. This is not ideal (I have to find the question and then find the answer).
Would be more convenient to save a sort of template/FAQ. So when I answer to someone on a talk page it would be nice to have a sort of personal FAQ. And a button below like "Save current to my FAQ". The list could be used to maybe append text to textbox. I could also see it as an accordion with textboxes (from which I could copy parts of text from previous answers)... Something along that lines.
