hi, it occurred to me, after writing a bunch of macros, that the other players might like the same macros to use for their logins, without the drudgery of typing them all out.
then it occurred to me that a dm, who would like rolls presented in a certain way, could write all the macros he wants, then send them to his players so their rolls are in his preferred format.
exporting and importing them would also allow them to be transferred across campaigns, which is apparently a niggling problem some people have had.
