I don't know. Most of the time I can't even find my questions to see if anyone answered them or not. Yeah, we have a question page, but the questions start the the questions you asked when you started. I'm still trying to figure out this system.
If you missed an alert or just want to check your questions. Go to your profile, Click on MORE + (Next to Activity), will give you a drop down menu--Click on DISCUSSIONS. This will show you questions from newest to oldest and list the last reply (User and Date)
I guess I never have paid attention to it, ben1011. I do know that a couple of times I've asked questions that have gotten no responses at all. (Well, that includes the time I was in Answerbag, too.) :)
