Don't think you have quite got the hang of this.Opening a link to NSC can be hazardous to a non-secure site,ie HTTP as opposed to HTTPS.Probably due to people posting with links to dodgy East European sites.I could be a **** and post the links,but unlike some,I have respect for other people.
In English ? I know about HTTP and HTTPS thank you. I repeat you can post links and it's not a risk to YOU !!!!
