Re: Changing default key

Hello,

My last post was sent before receiving this one. Thank you for the
pre-emptive reply :-)
I've just tested my key-generating routine by putting it in .pybrc.py
instead of Utils.py, and it seems to work perfectly. Python is a
wonderful thing :-) I'd ignore my previous suggestions to modify
Utils.py, unless you really want to change the configuration for the
whole system.

my new .pybrc.py is attached, and generates keys of format
AuthorBCDYY, where Author is the surname of the first author, B,C etc
the first letters of the surnames of subsequent authors, and YY the
last two digits of the year.

Thanks again

Dave
