As well as downloading CD descriptions from the Internet database you can also make them accessible for other users. In this way you can help improve the quality of the Internet database when you own a CD that does not exist in either the local or the Internet database. This does not apply to CDs with tracks you have compiled yourself. However since it is unlikely that anyone else owns an identical CD, entries about such CDs should not be uploaded to the Internet database, as this would create meaningless CD entries.
Note: When uploading CD entries remember that Internet databases are not normally updated immediately by the Internet database administrators as new entries must first be checked for plausibility. This means that if you upload a CD description today, it would probably not appear on the Net for several days.
