Hello I am a chinese american software engineer and made a platform in ruby on rails for you guys to post classifieds ads.
192.241.241.204/
Only students (with an edu email) can sign up to post a housing ad so you know the poster is safer.
There is a place where you can add a family/homestay and post a review of the homestay anonymously – in the future if you want to live with a family you can browse that list and call a number
All the ads will be categorized by area – so its easier to view
I already got some ads on my site.
I hope this helps and please share 
I may add more features if more people post/sign up for it.
got a problem/opinion/request please email me at firstlevelservice@gmail.com
