Hi

I've been using your Advanced Guestbook for many years. It's an excellent
tool, easy to administer and to handle. For a couple of month though, my
guestbook was being spammed with tons of entries from people who haven't
even visited the mainpage. A google search proved that the same comment is
being transmitted to hundreds of webpages by the same person within a short
amount of time.

This encouraged me to add even more security features to Advanced Guestbook,
such as:
- autoban: automatically ban ip-addresses that have posted more than a
certain number of messages
- check messages for similarity (I don't want to see the same text all the
time)
- allow only a certain limit of messages per day
- enforce loading of message form (as in version 2.3.4); plus enforce a
certain delay time between form display and posting of message
- logging of message flow (accepted and rejected messages) with optional
email notification

All these new features can easily be maintained via the admin interface.
They reduced the amount of spam in my board (www.freerelationshipadvice.com)
by more than 90%

As I think these enhancements can be helpful to other webmasters also, I
would like to share my version (named as 2.5.0) with you.

I am looking forward to hearing from you.

Regards
Markus Wepfer
