+=head1 NAME
+
+Blosxom Plug-in: antispam
+
+=head1 DESCRIPTION
+
+This plugin converts any email addresses in your stories into ascii code.  It 
+has no visible or functional effect, other than to change the html source code.  
+So something like this:
+       fletcher@hidden.domain
+
+Looks like this:
+&#102;&#108;&#101;&#116;&#99;&#104;&#101;&#114;&#64;&#97;&#108;&#117;&#109;&#110;&#105;&#46;&#100;&#117;&#107;&#101;&#46;&#101;&#100;&#117;
+
+But when viewed with a web browser, it is translated back into the expected 
+human readable string.  The idea is that some of the spambots can't read this.  
+Though as this technique becomes more popular, I am sure that the spambots will 
+catch on.  But it can't hurt, right?
+
+
+I would like to figure out how to get this work with Writebacks as well to hide 
+email address that are submitted, but haven't gotten around to it.  If someone 
+wants to modify the code and let me know, I can distribute the modified version 
+and give you credit.
+
+Let me know of any bugs!!
