Are duplicate speakers with the same name allowed?

Duplicate speakers with the same exact names are not allowed.  When adding a new speaker for the purpose of rating, the new speaker's name is checked against names of speakers in the database.  If the name of the new speaker is already in the database, the speaker addition will not be accepted; instead, the user is asked to add a unique description for the new speaker.  Speakers with similar names can be distinguished by adding a middle initial, by adding a unique speaker description, or both.

For example, the speaker names "John Davis," "John B Davis," and "John C Davis" are not duplicates.  The name "John Davis" with "Idaho senator" description, the name "John B Davis" with "Idaho senator" description, and the name "John Davis" with "Idaho carpenter" description are also not duplicates.

The terms speech and presentation are used interchangeably; however, presentation generally involves slides; oral presentation and speech are sometimes used interchangeably.
