[speaker001:] Do you know what the BBS is?
[speaker002:] Sure.
[speaker001:] Tell me then.
[speaker002:] BBS means Bulletin Board Service.
[speaker001:] Oh, I see, but what's it used for?
[speaker002:] A lot of things!
[speaker001:] Tell me in details.
[speaker002:] Okay. BBS, an online service, offers a wide variety of online games, files, one-on-one chat, message areas, private mail, and participate forums.
[speaker001:] Oh, that's great. I want to try later.
[speaker002:] Why not?
