I want to know what is going on.
What going on is quite simple, you have done your part by suggesting the site. There is nothing else you need to do. At some point in time (and it is impossible to determine how long that takes) it will get reviewed by an editor.
Is more than eight month not enough time to consider a web-site?
It is not uncommon for wait times to exceed two years.
And if whoever is in charge of the category for Las Vegas real estate is on up an up?
No one, repeat, no one is in charge of that or any other category. There are volunteer editors who have permission to edit in that category and there are several hundred editors who can edit anywhere in the directory.
I can think of two things that are not right immediately: your understanding of what DMOZ is about and your expectations.
DMOZ is not a listing service for webmasters.
You made a suggestion. That suggestion was put in a pool with others and will be looked at eventually. No promises were made with regards to timeline, no commitments were made with regards to a listing.
I can tell you a few other things: that Las Vegas real estate category is a sewer in terms of suggestions. You have industry colleagues who very aggressively spam the directory with cloaked sites, mirrors, fake addresses and the like (so much for real estate industry ethics). It is as bad as some shopping categories. You have a lot of real estate agents with offices outside of the city of Las Vegas who suggest their sites to the Las Vegas category in direct contravention of the rules for suggesting a site. Many editors who normally don't have a problem doing real estate sites shun the Las Vegas category for that very reason. When I was an active editall who specialized in Regional and live in the Southwest, that category was a perennial mess.
Bottom line: An editor will look at your suggestion
eventually. In the meanwhile, you might want to take a peek at the special guidelines in place for real estate sites (made necessary by those wonderfully high real estate industry ethics).
My web-site doesn’t need DMOZ for search engine rankings
Good, then you have no reason to get uptight.
