$settings['system'] - set to 1 if your website is on a server under Linux (most servers are), set to 2 if it is under Windows (your SERVER, not your computer!). If you are not sure which operating system your server runs under try with $settings['system'] set to 1 first or consult your web hosting company. If you are under some other OS (not Linux nor Win) you can try setting it from 1 to 3 and see if it works


$settings['apass'] - this will be your password for the admin panel. Change it from the default password admin. Use only letters a-Z, A-Z and numbers 0-9


$settings['website_title'] - A short title of your website, eg "My lovely website"


$settings['website_url'] - URL of your website. This is the URL your link partners will have to place on their website.


$settings['gbook_title'] - Title of your guestbook, eg "My guestbook"


$settings['smileys'] - If set to 1 text like :), ;) etc will be replaced by smileys (image icons). Individual visitors will still be able to disable smileys for their entry. If you don't want to allow smileys set to 0.


$settings['notify'] - If set to 1 you will receive an e-mail notification at your admin e-mail address every time a new entry is added to your guestbook. Set to 0 if you don't want to be notified.


$settings['admin_email'] - Your e-mail address where new entry notifications will be sent. Only required if $settings['notify'] is set to 1.


$settings['gbook_url'] - URL of the gbook.php script. For example http://www.yourdomain.com/guestbook/gbook.php


$settings['filter'] - If set to 1 all new posts will be filtered for bad words and replaced by ****. Set to 0 if you don't want to be notified.


$settings['filter_lang'] - The language of bad words file. For now only English language is supported so you can only use "en" (CaSe SeNSiTiVe). Please read section "Adding / Translating bad words list" further down for info on how to add/translate bad words.


$settings['autosubmit'] - Setting this to 1(recommended) will require entering a "security number" in order to successfully submit a new entry to the guestbook. I have added this to prevent SPAMing the guestbook. Set to 0 if you want to disable the security number check.


NEW: $settings['filter_sum'] - this variable is used in the preventing automated submissions and is just a little trick that should make it all even more reliable. The idea is to set this to some random sequence of chars and numbers, for example dhjx72js. It doesn't really matter how long it is, but you should use only chars (a-zA-Z) and digits (0-9). Don't leave the default value (as it would loose the whole point), set it to something of your own. Examples would be g3oyf98, p9ak85i, h398dgf and similar. Again, DO NOT USE these examples, just type some chars of your own!


$settings['one_per_session'] - if set to 1 each person will be able to make only one post per browser session. As of version 1.33 you can officially disable this by setting this variable to 0


$settings['max_word'] - The maximum length of each line of comments. This is to prevent long "words" like ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff from stretching your guestbook.


$settings['logfile'] - File where all the data (entries) will be stored (advanced users only). You may leave this as it is.
