How does a site get into DMOZ?
First, an editor must feel that the ODP needs more of that kind of sites. (This feeling is what makes surfers into editors, but there are lots of kinds of sites, and no telling what any particular editor will be looking for next.) You can't predict when this will happen, and you can't control it. (So if a site is waiting here, it is nothing you did.)
Second, an editor must be able to find the site. (Your site suggestion is intended to accomplish this.)
Third, the site must be "a likely candidate", that is, wherever he finds it, of all the sites remaining to be reviewed, it looks like the one most likely to be added. (This is largely random, since editors can't judge probabilities that well. Eventually we review most of the candidates including all suggested sites.) You can influence (not control!) this by writing a professional description, and suggesting the site to the best category.
Fourth, the site should be listable. It must have significant unique content. For user-supplied aggregated-content sites, the bar here is VERY high, and I'd bet 100 to 1 against any particular site. If a site is not high in the top 1% of all "classified ads" sites, then the user is better off not knowing about it -- and that is the only factor that matters.
