>> 
>> 
>> Hello,
>> 
>> I am continuing the research for the technical history of 
>> Telnet with Chris Edmondson-Yurkanan for the THINK Protocols project.
>> 
>> The goal of THIS email is to solicit some stories, opinions, 
>> regrets, deadends, etc. on the design (or early usage) of the 
>> Telnet protocol, that would add the personal touch to the 
>> story, help engage the novice reader in the subject, and 
>> perhaps better explain some decisions made in the development 
>> of the protocol.  The time frame for the story is mainly 
>> between 1968 and 1973, but any experiences after 1973 are 
>> also welcome.
>> 
>> I have included the outline of the story as a reference, and 
>> in case you are interested, the URL to the current version of 
>> the story:
