I've been submitting URLs to the directories for a couple of weeks. I decided to make a list (which is rather short so far) of instant and rather quick listing directories already proved by me. I kindly ask you, guys, to share links to such directories here.
Instant Listing Directories:
http://onemission.com - PR 4
http://www.canlinks.net - PR 5
http://www.wikidweb.com - PR 4
Free Web Directory. No Reciprocal link required. - PR 3 (these guys accept only one free link per day)

Quick Listing Directories:
http://www.abigdir.com
http://www.littlewebdirectory.com
http://www.viesearch.com
http://www.roask.com
http://websitespromotiondirectory.com
http://www.pegasusdirectory.com
(Some of them require reciprocal link for quick listing)

To be continued...
