How To Join FidoNet (Step-by-Step)

  1. If you are not already familiar with FidoNet/FTN systems, start by gaining a basic understanding of that and of your software. Download the POLICY4.ZIP document from a nearby FidoNet BBS, or from Read it thoroughly. Then read it again. Do the same with your software's documentation. You will also need a current copy of the Fidonet Nodelist.
  2. Set up Synchronet BBS. Make sure it operates correctly, to the best of your knowledge.
  3. Follow, to the letter, the procedure outlined in POLICY4 for joining Fidonet. The request must come in as a Netmail message. This shows the NC that your system is indeed capable of exchanging mail: the basic requirement for membership. Do NOT request a node number in a LOCAL message on your NC's system, it will only delay the process, and may even be simply ignored.
  4. Be patient. It may take up to 2 weeks for your request to be fully processed and appear in the Nodelist. Remember that your NC may not be able to contact you at all until your address becomes official.
