From '85 until '94 or so, I saved my transcripts from visiting the Amiga communities of CompuServe, PeopleLink, Delphi, Genie, BIX, the Well, etc.
I've thought about writing some code to parse these text files to reconstruct the message threads or file archives from these forums, and making them available on a web site.
Out of a concern for file space on floppies, I know I would often edit these text transcripts and remove posts that I didn't want to save - so I know I didn't save everything.
Did anyone else save transcripts of their ASCII modem surfing?
