#Log Submission

Log submission is the step in which a contest entry is delivered to the sponsor, usually as a Cabrillo file sent through a web upload form or by e-mail to a log robot. Each contest publishes its own instructions for file names, subject lines, deadlines and the e-mail address or page to use. A good routine includes checking the header, keeping the exact file that was sent and saving the confirmation message. Typical reasons for rejection are a wrong file type, a damaged header, an unknown category value or a late arrival. The articles under this tag explain how to prepare, send and confirm a log without last-minute surprises. They are written for contesters who want to be sure their entry was received and read correctly.
