We have a new site that's in beta now, the Web applications proposal. I've been committed to it (for a while), but I didn't receive an email with info that is was created. I only found out by posts here on meta, and the Area 51 site. I was able to create an account and everything just fine though.
I don't know if I'm the only one or if others didn't receive the mail notification.
Note: I did receive other emails from Area 51.
I received the mail this night. I'm not sure how delayed it was, about one day I think. Reminds me of snail mail, but at least it works.
