I'm new - and I have a stupid question!

Hello, I'm new, I'm from Montreal, I speak English, French, and a tiny bit of spanish.
My stupid question for today is: is there a place on the site where I can see all my last posts ? (a bit like the Preferences/Comments section on Slashdot) Because I don't want to have to subscribe to everything so I can see when people answered to my posts..

On the main page, check out View your profile in the Member Functions. At the bottom, you'll see Last 20 posts by user.

Great, and I get an email message....thanks a lot!
