User states she received duplicate emails about blog posts from our site and so is leaving

I just had a user delete their account because they said that they were receiving duplicates of every blog post and every posting. (I assume she must mean discussion forum posts)

Anyhow, she was willing to chat with me and her account is not deleted from the server yet. Basically when she 'deleted' the account it was disabled and is awaiting my deletion. However, I would sure like to know if you have any idea how I might be able to track down these outgoing email messages to figure out if what she is saying is true. Also, I would like to know if there are some settings I could set for her that would reduce the amount of email she receives from us.

Her account Username is: mrsplant

Thank you, Sean

PS. She also told me the second reason that she is leaving our site is that the interface is confusing to her. My guess is that is a combination of my having a 'busy' site as in a lot of stuff on the pages as well as the fact that we do not yet have one uniform navigation bar for EasyBlog, EasyDiscuss and EasySocial. So, I am glad to know that is in the works. :-)
