Okay, so I haven't been getting any alerts for about a month -- I have to log on and look at what stories I have on alert on my profile page (but I'm still missing all of my author alerts). On the site updates I noticed it said they would be doing this to e-mails they can't deliver to, but they didn't start that until a week ago and there's no way I would have missed any message from them - I check my e-mail practically every day! They said users would be able to log in to resolve the problem - but not HOW! I have no idea how many story updates I've missed since this happened (I don't necessarily add a story to story alert if I already have the author on author alert, after all) -- veeery frustrating!
Has this happened to anyone else?
