I submitted a site back in January, but I'm not holding my breath waiting for ODP to review it. An SEO website at the time said ODP had been taking six months to review a listing, and I don't know how old the SEO website info was.

If you're not paying for website submission, it makes sense to give ODP one shot per site, as there are few free search engine submissions these days. (ODP is a directory, but it feeds into search engines.) Yahoo now has a free search engine submission (but not a free directory submission), and I believe it was Yahoo who took over AllTheWeb and Altavista, who have both placed a temporary hold on new free submissions. The other two currently accepting adult site free submissions are Google and Lycos.
