Traders-Talk website and forums are now secured with an SSL certificate. This means that all data between here and your browser is encrypted in-flight.
Those of you who use modern browsers will notice that the site is no longer reported as 'Not secure' in the browser address bar.
This change might have meant that you were forced to login, when you weren't expecting it. Other than that, the change should be transparent to you.
