Founder here. Here to answer any questions you might have. The site is not perfect, it's not mobile optimized, there are probably bugs, there is a gazillion features missing, no APIs but it's a labour of love, open-source and I hope it will help people other than me. I want to grow this product but I need to know what you need, people. Edit: sorry for the bugs I see on my server popping here and there. Didnt expect that much users and traffic.
It would be neat if there was a demo. For this kind of stuff I'd rather not give my information till I know what I'm in for completely.
