  --- BEGIN ISSUE ---
  Links to company websites doesn't work without http:// 
  On a company profile page the link to the company's website will only redirect the user if `http://` is specified when the link is added in the dashboard. For example, the link to AppearTV is written as `www.appeartv.com`, and redirects to `https://online.ntnu.no/company/60/www.appeartv.com`.
  There is no information to the user creating an event to add http either, so I can imagine this being a growing problem.
