We just published a new update for Firebook, version 6.0.1 on the website which includes a number of small bugfixes and changes in our software. What is more, we have worked hard on the spam filter to make it even better!
 
To show you that we are convinced of our spam blocking solution, we deactivated captcha codes for our demo guestbooks! We don't need them because we have our filtering solution!
 
best regards,
your Firebook team
