This is the awesome community i have ever seen but I think this site have to provide a extra Checkbox in all the forums and allow the ranchers to save the topic they want into their folder by clicking the checkbox. I know this will put extra database burden but it will be useful to everyone to save the topic which they wants privately with them.
One more option... assuming that you don't like the JR bookmark or watch feature, is to use your broswer. JR topics generally don't change (and have redirects, if they do), so you can also use your browser favorites feature. And this feature generally allow you to organize with folder and file names.
