Thunderstone has taken measures to reduce the amount of spam its
employees receive. This may impact some Webinator user's ability
to obtain help via the listserve. We are sorry about this, but
we can no longer tolerate the volume of spam mail that we receive.
If you are located on one of the networks below, you will _not_ be
able to send email to Thunderstone. These networks are big
offenders based on our analysis of the annoying messages over
the last few months.
