We only can try to help you understand the DMOZ process.
First of all you can't submit a site to get it in the directory. You can only suggest a site to the editors. Sometime after you suggested the site one of the editors will look at the site and decide if it is listable, which we call review. You will not be noticed when an editor reviews the site, bot when it is listed and not when it is rejected. Once a site is suggested it will never be removed from the pool with site to be reviewed. So there is no reason to suggest a site more than once. If you suggest a site every few months to the same category the odl suggestion will be overwritten. And for those editors who review sites on date it was suggested you just put your site at the end of their todo list. But not all editors review sites in order of date. If you suggest a site to several categories you are spamming the directory, which may eventualy result is a ban of you and all of your sites.
So. You have suggested your site. That is good (if it is a listable site). There is nothing more you can do in relation to a listing of the site in DMOZ.
