I don't quite understand your example of the LogEntry object. However, check out the sample
code that is included with the log4net distribution. There are full examples that show how
to extend log4net. I have done it quite a bit and it works well. Yes it is easy enough to
write your own appenders that extend AppenderSkeleton, just examine the source code because
that's what all the appenders do, so you can just copy and paste.
