Hi there,
I created one Rails website in my spare time, http://remoteworking.info . It is totally free, for both job posting and ads.
I started this project two weeks ago and spent two hours per day to get it ready. It’s for remote jobs only, you can post full-time, part time and project here. Currently, it is ugly looking, I will improve the user experience in the future. Please give me your feedback and help make it better.
A lot of ideas in my mind and more features to be added, and I will improve it as per your feedbacks.
Hope one day I can find some remote job in the website created by myself, 
Cheers,
Y.
