Is there any way a user could be informed when he's being quoted, or a new reply is being post?

I find the current system quite confusing. I can't get in touch with the latest posts on the topics I've posted on, and I believe it makes me more quiet and passive on this forum. 

Also, where can I get a list of all my posts and threads? 

I would be very thankful if someone gives me a hint about these things. :)

It's right beside your avatar… as for posts you made, check it on your profile :)
