( Do they accept gambling website? ) They have round 2000 links ) I don't think they have tips for submission but long waiting list. Dmoz submission has to pass through many levels of editors to get there approve. If you have the chance .
I submitted 3 websites, 1 week passed and still no improvement...do they send you an email if your site is accepted or rejected?
Nobody bothers reading any threads before posting do they? Absolute rubbish. One editor usually reviews and accepts or rejects a site, just sometimes if they are not happy with the site meeting criteria or where it is placed an editor may ask for advice. In a word NO. If you want tips why not try READING the submissions guidelines (see my signature), you know the ones you say you have read when suggesting a site. Yes DMOZ accepts gambling sites, but it has the largest suggestions pool because it gets so many spammy sites and no editor wants to work in it. So expect that sites might be on the long end of all sites taking from a few days to a few YEARS to get a review and only sites that comply with the guidelines will be listed at that review. And a hot tip, don't submit more than once.
