I have the form page, because there people can easily contact to me. I had before every form in own site, but now I merged them. I made my form script on my own and I know that it will analyze information before sending that to me. I got spam through my contact-form, which is good and bad thing. I know now that there are visitors, but through the spam I added spam filter. If the script noticed that visitor sends me spam, the message will be marked and move to my spam folder. The script also affects on feedback form. If you want to send me feedback, it should be good. That's why I added char-counter and minimum limit.
My host, FriHost, collects information about every visitor. These informations are mainly about browsers and operating systems, like which version on which browser visitor used and on which operating system. This service also looks visitors country. This information is just for me to know useful information about visitors. I know through this how to optimize my site and do I even have visitors and where they aree from. This also was the reason why I started to create my site in English.
