Lord of the Rings, thanks a lot for your fast response!
I tried the links you gave me.
But the following error showed up for both:
Sorry. The administrator has banned your IP address. To contact the administrator click here

I googled the error message. Now, error is narrowed down to Proxy. I am using a university PC which is configured to use a Proxy server for outside connections.

Programming LimeWire seems quite relevant to what I want.
Any one, plz help me ... how can I pass through the error message and join that section? What should I do not be banned by the administrator?

Thanks!
