The BBS is now ready to go on-line. All it takes is a click on the "Begin On-line Operation" button on the main BBS control panel.
Of course, you can't tell if the BBS is really operational until a user successfully logs in via the modem/telephone. Assuming you don't have a second computer/modem to try it out with (most of us don't), you should get a friend to call in and try it.
Once it's been checked out on-line, you can start telling everyone the BBS is up and ready for use. And you'll want to think about customizing it.
