Help me get started

[vignesh]

Hello guys
This is Vignesh here. I have just started with Free Radius. I would like
to understand the working of Free Radius before I start experimenting
with it. We are planning to use Free Radius for developing a telecomm
billing solution both prepaid and postpaid. I am not sure where to start
from. Could you please help me out with it. If you have any documents,
samples and if you can forward It would be of great help. My email id is
vignesh at novanet.net

Thanks in advance
Vignesh
