The Concept: Each user on GreyHen has access to a favorites list, which lets them easily choose images they find while browsing to save for later. Each account can add up to 1000 images to their favorites list, and can have only one favorites list, with one exception - we'll get to that later.
Adding Favorites: The easiest way to add a file to your favorites list is to view the file you want, then click the yellow star in the top right corner of the screen. This will add the image you're currently viewing to your favorites list, without making you navigate away from the image. Note that you must be logged in to do this - if you don't have an account, you can make one here.
Viewing/Editing Your Favorites: To view your favorites list, go to your Homepage, click "Favorites". You will be taken to a page displaying all of the files in that favorites list - clicking on any one of them will show you the full-size image, and let you scroll between them. To edit the list, go to the page you were viewing all of the files from, then click "Edit" in the top left. This will give you a number of options for adding, moving, and removing files.
Extra Favorites: Running out of space in your favorites list? Want to keep some favorites separate from others? You can indeed have multiple favorites lists, but since they take up so much room on the database, it won't be free. It will, however, be cheap - for every dollar you ever donate to GreyHen, you'll get an extra 1000-image pool! You can donate here. Once you have multiple Favorites lists, going to the "Favorites" section of the homepage will show you all of them, and let you choose which one is the "default" for new files to be added to.
