a complex IRC bouncer which at the time boosted popularity of BNC services. While working for GamesNET.pl I was responsible (among many other things) for enabling a subscription-based BNC service for clients using QuakeNet.org IRC network. While completing this task I managed to heavily modify the existing PsyBNC codebase to make it suitable for use within GamesNET.pl. Most significant modifications include:

• the ability to fully configure a PsyBNC instance remotely
  • Polish translation, in versions without special Polish characters, as well as in ISO-8859-2, CP-1250 and UTF-8 encodings
  • simplification and unification of the interface
  • security hardening of the service
