I enabled password and all below.
For security reasons, you may wish to display the IP or Hostname of the person signing your guestbook. The default is ON.
Enabled - If you want to password-protect the comment feature, set this option to 'Password required'.
Reduced - Message Length
You can set the minimum and maximum message length here. The max. word length is an option to avoid messages from nice people entering a bunch of characters without spaces
Increased Time - FloodCheck Time Span
Set the amount of time in seconds used by FloodCheck to prevent post flooding. Recommended: 60. Type the number of seconds only.
Tried to enter IP in the - IP Number Ban List:
Put each IP number on its own line. I'm doing something wrong here. Seems when I enter the numbers and click submit changes, ip numbers are gone from the ban list.
We, mouse and I look forward to eliminating this invasion on the guestbook.
