I've just joined Exbet today and I have to say you've done a very good job, it's the closest thing to betfair. The website is quite smooth and easy to navigate, but the liquidity is too low. Hopefully that would pick up in the future. Just one thing, I noticed that the site keeps logging me out every couple of hours. Usually people spend lots of time on betting exchanges and the most annoying thing is to get logged out in the middle of a match. There should be an option to keep users logged in.
