SLUG? From no one. UTS pays for it.

Both Hunterlink and Spectrum (or it that newtreno?) were our previous
mail providers. They did SLUG a great service; earlier in the month
we consoldiated the email lists onto one machine. That machine is hosted
at UTS.

If you (or other posters) set Reply-To when you emailed if probably wouldn't
arise as a problem. It is easier for the original poster to type in where
they want responses than for a (potentially) unlimited number of respondents
to edit their header fields.

ProgSoc can't provide exact figures for our bandwidth consumption but we
use surprisingly little. Apart from the large spike on Tuesday not much
has happened. Also the network we are on is shared by a few other machines
too.
