Smotri is a Russian based video sharing site which also features the option to broadcast live cams. The broadcast section of the site is very active, though for the most part all video chat is in Russian, but hey you can always try some English.
To access all cams on Smotri, there's an adult section, you'll need to sign up, but that's free and easy.
Smotri Sign-up Guide.
To register click the first of the links in the very top right hand corner, enter an email address and continue with registration.
To login after registration click the last of the links at the top right hand corner, you should get a pop-up login thingy.
To access the broadcast section look for Трансляции near the top of the page, and if you want to access the adult section look for Эротика near the bottom of the left sidebar.
You may have to fill out profile information such as age to access all of the site, I can't remember, it's been a long time since I signed up to them.
