@reply-all is a list.serv/mailing-list software that modifies and maps emails sent through its system to target users whose previous contributions most match the current email. Through this process @reply-all modifies/augments communications that are routed through the system.

Emails can be sent via reply@reply-all.org or from the webmail client.
When using the webmail client, the system actively prompts suggestions/similar phrasings that previous users have entered. If supported by the browser, `Tab` will inject these projected matches into the insertion point and advance the cursor to a new sentence.
When emails are sent to reply@reply-all.org, they are modified/encoded when received by the system via quotation/versioning using email-client methods of showing replied text.
Both methods address the email to other users whose emails are most similar, based on factors of length, content, and similar word frequency.

@reply-all is also an archive of the texts that have been sent through the system. The process of viewing archived emails further transmogrifies/transforms them by readdressing the contents, much like biological memory, by applying both more recent and older emails to the specific email being selected. Mutations in the text are in [brackets] and italicized.
