Notice to those seeking student worker positions

Each semester I typically receive dozens of cover letters and resumes via e-mail from students seeking employment. This is fine. However, any attachments sent in Microsoft Word format will be summarily deleted. If you want your resume read, then either send it as PDF or plain text.
