I used to use a bbs offline "mail" client called blue wave, and it would import .qwk files from the bbs, then you spent your time replying offline and in the end would upload a .rep package containing said replies.
In some ways I miss it but in other ways I have a 500/500 internet fiber connection now and do not miss the days when donloading a 10 mb file took the rest of the day.
Dialing up every morning, exchanging QWK/REP files, getting off as soon as possible was my first forte into scripting things.
Sigh.
Funny how things have reversed, now we are the ones with unmetered fast internet and the US has datacaps and whatnot.
In the late 90s, pre DSL, there was a pressure group to allow unmetered phone calls. The site is still online: http://www.unmetered.org.uk/
I remember the late 80s and early 90s as an absolutely wondrous time; using the computer as a means of connecting to someone else somewhere else was a little bit mind blowing.
I just spent a few minutes going down memory lane looking at the BBB's on this site: http://bbslist.textfiles.com/503/ remembering some of the door games I used to play.
