Hi there, you can keep track of all of the threads that you've made by clicking on your username from one of your posts, and there, you can find options, like seeing all of the threads that you've started, or even the posts that you've done. Or in other words, click your own username, and click "find all threads by EClipZe-Chayce". Or, you can go to your own profile, click the statistics tab, and you'll be able to see the same options.
In addition, you can also subscribe to all the threads that you've made, or a few of the threads that others have made, by clicking on to the 'Thread Tools' tab on the top of the first posts of each thread, which all will be shown in your User CP (well, when you click on the User CP). There, you can see the newest replies that people have made in each thread that you've subscribed to.
Hope this helps~!
