title: Activity Diagram: Continuous activity triggering event
body: <p>I'm having trouble modelling a continuous event as well as an activity that happens as part of that continuous event.</p>
  
  <p>I am modelling the tracking of a website by a Marketing Automation platform. However the tracking is a continuous event constantly happening. A part of this tracking is the 'form submit'. This however triggers a new flow of activities creating a contact in the CRM.</p>
  
  <p>Questions:
  1. How do I make an activity in 'Tracking' invoke a new flow of activities if a form is submitted? 
  2. If I model this by using a fork: both (Tracking and form submit) need to occur before the flow is continued. </p>
  
  <p>I basicly need a fork where one flow is optional.</p>
  
  <p>Kind regards,</p>
