A system and method for reformatting chain forwarded and chain replied electronic messages into thread-of-discussion messages for improved readability and reader comprehension. The chained electronic messages are parsed into discussion entries which are then sorted by a preferred order, such as last-to-first by date of creation. Extraneous fields and data which are not part of the substantive discussion are removed from the discussion entries. Long or full electronic mail addresses are replaced by abbreviations or preferred nicknames which may be found in an address book. Finally, the sorted discussion entries with source abbreviations or preferred nicknames are combined and output as a thread-of-discussion format message.
