Overall quite useful service and quality implementation. I like it.
My suggestions are:
- add registration via Twitter
- use Telegram
Good luck

Good idea I think some people will be interested in that vitur, and social media is a great power to introduce this web.
I support it and there are thousands of others will follow it on facebook or twitter.
Hey, not sure about twitter, because i have done some work in twitter, and its quite useless i think too much noise.
As for Facebook here is the page
