While not as sophisticated as the above, a simple way is BBS Server, which allows access from the Amiga via null modem serial cable through a winpc connected to the internet. Its a modem emulator, easy to set up, and works well. You can connect to BBS's, check email, chat etc. Download it from a real C=64 BBS, link below. Instructions on pdf are there also.
