I have noticed that there is considerable disagreement about which conventions should be used in special and general relativity for such things as: the signature of the metric, whether certain tensors should be defined as covariant or contravariant; whether they should be tensor densities or ordinary tensors; where the c for light-speed should appear; etc.. Consequently, I feel that there is a need for me to set forth my personal preferences in these matters which I do in this file.
