Flow Survey

We are presently considering the purchase of a sorter, and are frustrated
by the difficulties involved in trying to compare the relative merits of
the various machines (apples and oranges?) on offer. Our difficulties are
magnified by the fact that we are purchasing the sorter for a user group
with diverse interests, and expertise which varies from considerable to
zilch.

To try to aid our decision making, we hope we can persuade some of you to
complete the attached survey. Our intention is that for most points, or
for most of those you wish to respond to, you score your satisfaction with
the feature, on a scale from 0 to 10.

0 Not applicable
1 Totally unsatisfactory
2...4
5 Satisfactory
6...9
10 Brilliant

A few questions require descriptive replies.

We will, of course, guarantee the confidentiality of any specific opinions
offered, but equally would be glad to provide summary results to any
respondents.

I have never tried to send such a long message before. Will it be more
than the bulletin board can chew?? Fingers crossed....

with thanks
