title: Send message to multiple tagged user
body: <p>How to send a message to multiple user by tagging.</p>
  
  <pre><code>@bot.command(pass_context=True)
  async def ping(ctx, member: discord.Member):
          await bot.send_message(member, "Pong...".format(ctx.message))
  </code></pre>
  
  <p>So above code works perfectly when tagged a single user <code>?ping @user1</code> but how to make it work when we tag multiple users <code>?ping @user1 @user2</code>.</p>
  
  <p>So is it possible to make it custom message given in channel not in script. example: when we type <code>?ping @user1 @user2</code>  bot should ask a message to send, when we add a message it will forward thet message to tagged user.</p>
