The DMOZ guidelines clearly ask you to suggest a website only ONCE to the ONE BEST category.
Please read our FAQ for more questions and answers about suggesting a website. (link at the top of this page)
Just once, in the correct category, is sufficient, thanks.
An editor will eventually review the suggestion and take appropriate action; But when that will be, no one can tell, given our volunteer structure.
In the meantime the best advice anyone can give you is to forget about the directory listing, and maybe have a pleasant surprise in the future.
