Four Web Utilities

I've recently developed four new super-specialized Web utilities for about six people out there in the big world:

CountDuplicates.com - Enter a list of lines and it will tell you how many times each line appears in the list.

FilterLines.com - Enter a list of lines and it will remove any lines except those containing the word or phrase you enter; or it will keep only lines containing the word or phrase you enter.

RandomizeList.com - Enter an ordered list of lines and it will scramble the list.

DeDupeList.com - Enter a list of lines and it will remove duplicate lines.
