Hi, I love the guestbook but i have problem. People are spamming and leaving prono sites into my site, i have been banning their IP but they are alot of them mostly like russian lagnuage. I want to know how to get rid of the people who are signing or maybe i could put a picture code so no computer hacker can spam my guestbook, i don't believe that they come to my site because i check the stats of the site, they are just leaving links some how i don't know how...please help thanks:)
