It is known that any site without feedback from visitors will not live long. If we talk about the blog – then it is no problem. Visitors can leave comments to the author, and sometimes write their notes. But if it comes standard site for any subject (the site of a famous actor, singer, a collection of games, music, story about his hobbies, etc.), then the feedback from guests must be added to the site or the forum or guestbook knigu.Forum on a small site looks awkward and deserted, and spoil all impression of the site. It is sad to look at dozens of categories, each of which added two or three posts without comments. Therefore, for a small audience recommended that you install the guest book.

A fresh review of the scripts and services guestbooks on the internet I could not find. Joel and Ethan Coen addresses the importance of the matter here. So I had to go through trial and error, resulting in a made certain vyvody.Dlya Starter experienced webmaster I recommend a dual-track decision – service guestbooks ModernSite (project started on site modernsite.km.ru in 2001), for which is available free script guestbook MBook.

And to minimize the burden that has script server. Otherwise, in a 'perfect' day Your hosting provider will ask (politely asks so) in connection with the increased workload of your scripts to switch to more expensive data plan, or at all, a dedicated server.Tak that my recommendations are as follows – use scripts developed by professionals. Fortunately, that there are many even in the free version.
