It is annoying enough that I am considering doing it too, because OMG it is so annoying. It probably wouldnt even be so bad if they came at the same time, but like, I will get 1 PM today, 2 PM's tomarrow, and 3 PM's the day after that. In like 5 days In 5 days I will start to get emails telling me about the PM's I got 4 days ago. It's sooooo annoying.
But seriousely, dont use someone else email - I will get int trouble for mentioning it. It was a joke.
