Hi. Suppose I have a huge list of email addresses, in a file. I want to make sure that one email address doesn't appear in that list twice... so that, for example, user@aol.com and USER@AOL.com and UsEr@AoL.CoM are all considered to be the _same_ address.. take the "unclean" list, feed it to the case insensitive hash and print out the "clean" list. :) any ideas on how to do this, or if this is a good way to do this?
