Drupal taxonomy multi-select default value

I'm using drupa开发者_C百科l 6.16 and have a set of taxonomy terms that are set up as a multi-select box. I would like for the first item to be selected when the user loads the page. I dont know if I need to add code to a file or just simply change a setting. I should warn you I do not have a lot of experience, but would rate myself as a low intermediate level programmer.

Thanks in advance msindle

The Taxonomy Defaults module looks just the ticket. Some more details about this module (from its project page):

Taxonomy Defaults allows you to assign default terms from any vocabulary to any node-type. The default terms will be pre-selected on the /node/add form, but can be edited.

If a vocabulary is marked as "Hidden" for a particular content type, then that vocabulary will not be shown on the /node/add form and the default terms will be assigned automatically and cannot be edited.
