The Base Config 090320

[Siamesecat]

I just looked at the cfg file from the base config zip file, and I have some questions about it.
What are extrange characters? I could not find a definition for the word extrange.
Why do the names of some of the filters have a long string of "N"s?
Why would you want to log incoming images?
What does the filter to log incoming non images do? Are you really going to log anything that is not an image?
There is a header filter called "Add to protect list". From what would you be protecting the browser? What sort of things would you put in there?
