Rose ann,

You can go to your profile and click on all threads which are the posts that you have commented to. Another thought is to write down the name of the thread you would like to revisit. Right now, I do not think that there are options to save them by folder. I will have to do some further checking on this.

One thing that you can do, if you save favorites on your computer. Click to add the specific webpages to your favorites. I hope this helps for now!
