The owner field will automatically show your Pennkey name, this cannot be edited.

Unless you are creating a post from scratch, the title field will always be populated by the title of the webpage, article, or book. The title that will appear is the title that PennTags has imported from the resource you are posting. This field is editable so that you can change the title to be more descriptive if you need to.

This is the web address of the resource you are posting. Unless you are posting from scratch this field will automatically be filled with the URL that PennTags imports from the web for the resource. This field is editable so you can change the URL to accommodate DOI's (link to DOI section) or to repair broken links.

In this box enter tags for your resource. Tags are descriptive words and you can enter as many as you like to describe your resource. Separate tags with spaces and if you are using multi-word tags join the words with an underscore e.g. instead of typing in New York type in New_York. For more help on tags visit tagging tips section (link to tagging tips)

These are two lists of your most recently used tags and your most heavily used tags. To add any of these as tags to your current post just click on the tag.

By default all posts added to PennTags are viewable on the web by anyone in the world. If you want to keep your posts so that only you can view them select the "make private option". See the privacy policy for more information

At this point you have added all the basic information that is needed to create a post. You can scroll to the bottom of the posting page and click submit to add your post to PennTags or you can fill in the rest of the form to make your post more descriptive.

Use this field to add notes about your post. You can use notes to explain, describe or add further information to your post. Use the tools at the bottom of the notes box to format your notes.

Use the pulldown menu to select one of your projects into which you want to add the post. This list is of all projects that you have already created. If you would like to add your post to a new project, you should add the post to PennTags without a specific project. Then create the project later in Penntags and add the post as described in the Project section
