I like that it's very easy to use and set up. It also has many options for controlling comments, including allowing or blocking certain IP addresses, etc. There is nothing really bad about this software at all! You can't get any more helpful than that! We have been able to eliminate so much spam with our site by using this software.
The only thing we are not happy with is when you delete posts or threads they don't go away immediately (you need to refresh your page). That's just one of thoseβ¦
