HERE IS A COLLECTION OF PORTALS TO USEFUL LINKS
This saves you the trouble of looking for them via search engines that
track were you go and what you do there.
My website does not track where you go or what you do on the World Wide Web.  
If you would like to add a useful link to one of the portals, send me an email (iq@manyportals.info)
Note: If you get a blank page when you go to a link, your browser might need to be upgraded.
And that is because some websites are now using json in javascripts.
