I don't know about you but I am beginning to find the combination of digital camera and computer invaluable for putting together articles and letters quickly while the subject matter is still fresh in ones mind. Obviously the most convenient way to submit such material is by email.
However, while my postal submissions to SEM have always resulted in a prompt acknowledgement of receipt by postcard saying whether or not the material is likely to be of use, emailed material does not seem to be acknowledged and my recent piece on the Villiers Mar-Vil apparently rattled around Kelsey Towers for some time looking for a home before disappearing altogether and only resurfaced when Eric Brain got involved and asked me to resend the whole thing!
This may have just been bad luck, but it is equally possible that I got something wrong in the first instance. It would be most useful if you were to publish some guidelines for email submissions; what address to use, preferred text and picture formats, max/min picture size and resolution, any limit on overall size of files etc etc.
