Sorry about that, the link included my username. So that may be why it didn't work. But what you can do is click on Account (at the top right) and then click on "My Profile". Then click on notifications.
There you can suscribe to different forum threads. But the blog is probably where you want to go to keep up on product updates, etc. Go to notifications --> Tags. Then under Symantec Blogs, click on that to expand it and select Encryption Blog.
That will allow you to select the frequency as well as the type of emails that you receive from Symantec about this.
Anytime there is a major update or a critical notification. We try to add a blog entry about it. But to subscribe to certain categories of the forum, such as PGP WDE for Mac would not be a bad idea either so that you can keep up with what is going on out there.
