ModelsHotel is good, must be able to verify that you are a model, just launched in June and posts events, most are in New York.  I went to the site and sent them my info.  I got invited to MOE in Manhattan and some other VIP events.  I recommend this site if you want to go out and have fun in NYC, and network with models only.  www.modelshotel.com  www.myspace.com/modelshotel
