Craigslist does not have many ads anymore. Well they have alot but not as much as before, I haven't been able to find what I need nor post what I have to offer half the time. Are your ads showing yet?
The other day I submitted my ad to craigslist, but my ad did not show up until the next day. Maybe they made some changes on their site. A while back when I posted ads to craigslist, it showed up instantly.
my add showed up instantly , but I just psoted only one ad. May be its the case if you are gonig ot post so many ads.
