You can visit your list of Projects here to see all items, even if they are set to 'public' or 'private', in order to edit them; only you can see this page. Select Edit against the Project that you'd like to tune-up and then remember to hit save to commit your changes.
Your projects can have up to three tags (for example; art direction, graphic design and artwork). This comes in handy when using Network as you can only send in relevant projects to a Network channel.
You can give your project a title, also. This will make it easier for you to distinguish your different projects, both public and private.
