don't know if it works?

I enabled v.6 module, set pingpong value to 1, history for 14 days and 3sec for user to count him online. I also enabled Current Session ID.
Then i tested it from 3 of my computers. After 24 hours there is stil no notifications in history, neither were any from my accounts blocked, as should be.

After second login from a different computer account should be blocked or at least warned. I think i am missing something here. Thanks for helping and good bye;)
