Andy,
 
At leas one of our members has been in touch with the developer and made
requests to simplify the cut and paste options of the text transfer.  
 
There have been numerous updates, and the text transfer has been updated
to make it more adaptable for use  to insert blocks of text for
broadcast.
 
All the other functions of the BSR and FIX apply to the text function.
 
If you were tasked with sending the participants of a net a rather
intricate set of instructions, taskings, or specifications, and had to
be sure each member had received it properly, you could spend a major
part of an hour with requests for fills or repetitions, words
phonetically, groups, or numbers.
 
With easypal, you get what you get on the original transmission, and you
send the BSR (Bad Segment Request) and the sending station sends the FIX
file containing only those segments.  Each member receives benefit of
any bad block that they missed in a FIX file sent to another member,
since it is a broadcast (non-connected) protocol.
 
If you were involved in dial-up file transfer in the 80s, when text
files were "captured" you will remember that it took as much time to
capture a space as it did a letter.  Transfer protocols were created the
compressed ASCII on the fly to improve through put, I seem to remember
J-modem, I-modem, y-modem and others that had the compression routines
built in.  I remember using a shell on ProComm Plus to allow choosing up
to 14 different transfer protocols, dependent on the type of file you
were transferring.  I had at least 9 options available on the BBS I ran
from the late 80s to the mid 90s.  
 
If Easypal can send a perfect high resolution picture in a 20K Wave
file, you can imagine how small a 2 page document would be when
converted to binary, data digitized into a wave file then sent in this
manner to assure error-free reception.  
 
The repeater function allows the file to be sent to a central repository
then retrieved individually by the members who could retrieve the file
list.
 
The program is getting very polished, and has great potential. 
 
I don't know if it is getting much exposure in all regions, but it is a
valuable tool for the toolbox.
 
As far as acceptance, MARS is a fairly diverse group of folks.  Some are
up in age, some are retired and homebound, some are fit and ready for
deployment at the drop of a hat.  Since there are requirements for
continued membership, participation requirements, reporting
requirements, requirements for pulling NCS and ANCS, requirements for
NIMS compliance, now the requirement for a General or higher license....
Then you can see that the members have to meet certain obligations and
benchmarks to continue to be a member.  With this in mind, the program
has some fairly receptive members, who wanted to go further in their
service in, and understanding of the art of communications..  Most of
them are quite willing to try something new.  
 
We haven't spent the degree of time on Easypal as we have with MT-63.
But with each region having up to 10 one hour long nets scheduled each
day, and each net has the requirement for some sort of training, and
many members are uniquely qualified in one aspect of the training or
another, it becomes fairly easy to see how a new mode can be introduced,
explained, setup and operation help given, and results seen within the
course of an hour and in an interactive manner in a disciplined net
structure.
 
Is MARS the silver bullet?  Hardly.  It has it's growing pains as much
as any organization.  
 
In Amateur Radio, if there is a community that has 3 Amateur Radio
operators, there will be 4 opinions on every subject and pretty soon
there will be the need for 5 repeaters to be established so they can
communicate with their "group".  We all can key the Mic, but many times,
as "communicators" we show that we can send out a signal, but actual
communication is not often what results.  The organized format of MARS,
the requirements, continuous training, forward looking (not driving the
car by only looking through the rear-view mirror), the disciplined net
structure.  All of these things help form a group that is dedicated to
the art of emergency communications.  Once that subset is created, most
of the QRM is left behind, and they can concentrate on the task at hand.
 
Overall, I am usually fairly happy to be associated with MARS.  
 
BTW, the General class or higher requirement was recently introduced,
with the main purpose to allow interoperability with ARES, RACES and
other Amateur radio groups.  So we would sure like to see some organized
effort for both groups to start working together.  
 
As usual, far more of an answer than you requested, but maybe some extra
content slipped in that makes the big picture more visible.

David, I am interested to learn of this. Rick , myself , and several
others in this group played around with EasyPal a year or so ago, we
also thought it had interesting uses for file transfers. How it are MARS
folks accepting EasyPal?
