Whenever posting on these forums, please give us as much information as possible. Things like the operatings sytem, etc. In your case, the procedure might differ depending on the browser you are using.
As an example, IF you're using Internet Explorer, click on the link below which will take you to the "Computer Newbies" main page.
Once there, click "Favorites" in the upper left, choose "Add to Favorites" from the menu that appears. When the next window pops up, make sure the name of the bookmark is to your liking, then click on OK.
That should do it. When you next click on "Favorites", you will see your bookmark. In the future, if you want to get a little more complicated, you can add specific folders to the "Favorites" section and add bookmarks in their appropriate folders.
Hope this helps.
