This is not exactly Google sitemaps (although the format is the same), so if mods know a better place for this post, please move, I just could not find one. Anyways, moreover.com sitemap pings used to be the way to let MSN know your URLs. Nnow Bing has its own pings. Moreover still accepts pings (although I'm not sure what it does with them). So, do people still ping their sitemaps to Moreover? For that matter, where else you ping other than the big 3 (4 including Ask)? Thanks!
