2-20 minutes depending upon the quality of the application. You might have been asking about elapsed times before review. Because these depend entirely upon the availability of volunteer meta editors or catmods, they aren't predictable. They are quite long at the moment.
I think you need this link Jim, you have left a link via editor login http://www.dmoz.org/editors/manage/getmetalist?start=0. Strange though I used that link I had to actually log in before it would let me through. Anyone not an editor trying it please tell us if it goes where it is supposed to do.
Ah, your link isn't going to work for non-editors either . Sorry folks. With the introduction of the DMOZ 2.0 back end, I can't find a public link to the list. I'll enquire.
There is no editor review time. Depends on the quality of your site and the time the editors have to put into reviewing sites
Just in case Jim is not passing this way for a while......Yes you will get a reply and if you don't then you can read and ask about it here http://www.resource-zone.com/forum/index.php?showforum=10
