Is it just my e-mail or the system? I posted a question today in the morning, and I was waiting for someone to help out with the problem. I kept my yahoo page open and checked my email every 2 hours...yeah, I really needed a response. I didn't see anything in my email box till 4:43. This was not an issue. untill I went to check out the thread after the notification. The surprising thing was that 3 people had replied to my post, but the email notification of the response to my post was from the first helper at 2:43 not 4:43. The last person to help me out had posted at 4:30. What is going on with this? Is it PF? I used to check my email so I didn't have to keep coming back to the posts when I asked physics questions, and it was working lightning fast, back then. Just curious. I'll have to go back to the thread everytime, instead of going to the email box.
