Before the web and the widespread use of the Internet, computer users shared programs, news and other information over Bulletin Board Services. Those of us with a few grey hairs will remember connecting to remote computers using point-to-point connections using modems - I started with a 9600 baud modem before moving eventually getting a 56K screamer that let me download a 4MB program before my 60 minute time limit for guests ended. Well, the BBS is back.
