Log4Net has a new home
The Log4Net project has moved over to Apache. You can now find them at
http://logging.apache.org/log4net/index.html. They've been pulled together with all the other Log4* implementations at
http://logging.apache.org. So you've now got a one stop shop for Log4J, Log4Net, Log4Cxx and others. It also looks like they beefed up (or maybe just better organized) their documentation and manual.
