I'm not super techy either.... but maybe this can help. There is a strip just below the Thread name that has 'thread tools', seach thread' and 'display'. Click on 'thread tools' and a drop down list comes up. Click on 'subscribe to this thread' and it will give you a list of your bookmarks and subscriptions. You can choose which one you want the selected thread to be saved in.
Then, when you want to look at what you have saved, click on settings along the very top of the site.
Good luck. Maybe someone else will have another, easier way to do this but that's the way I've done it.
