Help Reviewing our New Website - Craigslist Competitor

Hello everyone, this is my first post on MCC discussions, but I have been a member for some time.  Sorry it took me so long to get involved!  So here is my ask...

We recently launched a new website, HavorNeed.com.  I am looking for your honest, brutal feedback on the site, design, its user interface, pretty much everything.  And of course if you like the site, please use it!  I don't want to say too much about the site because this will allow you to form your own opinion and tell me if it does a good job explaining itself.  

I will tell you that you do need a Facebook account right now to login and post on the site.  This is because we are trying to build a site with more security and better clarity of who you are dealing with.  If you don't have a FB account or don't want to use that to login right now, I am sorry.  We will be upgrading that in the future.

I am including two links below.  One is to the main site and another is to a landing page that we are using in targeted advertising.  Thank you so much for your help with this!

Main Site: http://www.havorneed.com
