Le site computerweekly.com est-il sûr ?

However it's registration will pick up your email address (not sure from where on my computer) and won't let you change it. I prefer to filter my work email by having a separate gmail account for external reference information to keep down the clutter and distraction. In addition, its opt out is unclear. Though if you don't want to pass your details to supplier, its a "don't read their content", the meaning of the "check this box for email" is ambiguous - does it mean I'll only get content via email instead of post and phone or does it mean I'll start to get it?
