The calendar shows my availability for fieldwork. I've been using this system very successfully for 4 years. If you are constructing field schedules you will be able to see at a glance whether I am available to help you with your work. Days and times identified as "busy" indicate that I am unavailable.
You cannot book my time directly using this system -you will still have to contact me. I will not agree to include speculative work in my schedule, the work has to be real and confirmed. We will also have to agree mutual terms.
