The database entry form asks for a lot of information. What if I don't know some of this information? [1]

Don't worry. The only required field is the "Title" field. All other fields are optional. How much information you provide is up to you. If all you have time for is inserting a link to a relevant posting on the Internet, or uploading a relevant document, it is OK to simply create a "Title" and then upload the document (in the "Relevant Documents" field) or insert the link (in the "Related Links" field).
