Preferred format is plain text since we format it for the journal anyhow. If you want to format it yourself, please download the Word Template and place it in your Templates Directory. Be sure to send it in time and make sure you have a valid return address in case I need to ask you for more information. I'm afraid we can't accept anonymous data or queries. Any pictures you might want to include should be jpg format.
Zip files are OK as are most word processing packages.
