While I'm familiar with Area 51, it's not a section of StackExchange that I trawl through very often. So, I often find that there are new Beta sites for Area 51 projects I didn't even realize existed.
Of course, many times, these sites will be about subjects which I have no interest in. Sometimes, they will be things I just have a passing interest in - not quite interested enough to be a regular contributor, but it's still a StackExchange site I'd like to know is around for me to check before praying to Google. And then, of course, there will be the occasional gem that represents a subject I am very interested in - something I could be a strong contributor to in some form, and would like to help grow.
So, my question is: Is there a way for StackExchange users to choose to be alerted to when any Area 51 project (not just projects they've committed to or followed) goes into Public Beta? If not, I think this would be a great feature to add in order to attract users to the Beta site.
I wouldn't be surprised to know that this is something that gets posted to a blog somewhere regularly, but I don't really follow the blogs myself except for what posts get bumped into the chat rooms. So, I believe the feature might be a bit more useful if it was implemented via some sort of e-mail alert or a notification in the Global Inbox. Again, this should be an opt-in feature.
Is this something already available, which I'm not aware of? If not, could it be implemented in some form?
