"Agora, for those who cannot be in the Arena"
A part of WWW history, sadly (?) gone.
Agora the name of a WWW-E-mail gateway, written by Arthur Secret of W3C in 1994 (when access to web browsers was, understandably, not that certain). Last version was released in 1997. Although the source no longer seems to exist at hand, Agora appeared to have been written in Perl. (Reasonable Agora imitation could be written in Perl easily, though...)
The operation was simple: People sent message to Agora system E-mail address with body that said "SEND (url)". It was also apparently able to parse its own responses so that people could just reply to the message and tell, from Lynx-style reference list, where they would like to go from that page.
Along with sending formatted documents (send, www) It was also able to send replies to other addresses (rsend), send a lot of referenced documents as well (deep), and send document source (source, rsource).
