I don't know if this is already in use, but it'll be goo if a user could see all the topics he/she has posted in in their profile. If it's already there, please tell me how to access it.

There are times when you will miss what you never had. I wonder how you will find what you so desperately need.

Go to your public profile then click on Show all posts by [username].

And if you want to see your posts on a specific thread, go to said thread and scroll to the bottom. The numbers there represent your posts.
