I don't know if I read it in this thread or not, but I read that the tags only last three days or so, whereas the PMs will last until the person opens it. I guess that would only come into play with readers that only read fics on the weekend. They may miss some tags. Okay, I just got a shock to my system. I have been working and working with my son to get his spanish grade up from a C-. The school sends me his grades everyday via email. So I look at the email today and he has an F in the class! I freak out and go to the school website to see how he went from a C- to an F in one day...and I can't find the F. So I go back to my email and I read it again and it was a C-...not an F. Where did I get that F? I am going crazy. I'm seeing things.
