title: Unwanted page break after \maketitle
body: <p>I'm trying to remove the page break I get after the abstract section in a research paper. What could be wrong in my code?</p>
  
  <pre class="lang-latex prettyprint-override"><code>\documentclass[preprint,pre,floats,aps,amsmath,amssymb]{revtex4}
  
  \usepackage{graphicx}
  \usepackage{bm}
  
  \begin{document}
  
  \title{A Blockchain-Based Approach to Identity Management for the Aviation Industry}
  \author{BlaBla}
  \affiliation{Chair of Quantitative Business Administration}
  
  
  \begin{abstract}
  Some texts 
  \end{abstract}
  
  \maketitle
  
  
  \section{Introduction}
  \label{sec:intro}
  
  some text
  
  \end{document}  
  </code></pre>
  
  <p>I want the introduction paragraph to be just below the abstract and not in a new page. And if anyone knows how to put a small space between the \affiliation and the /abstract that would be awesome too.</p>
