+REGEX:
+
+Yes, the chat supports regular expression filtering of messages. As regex tends to be difficult for most people, I decided to give it an extra section here.
+Regex is very powerful and can be used to filter messages that contain certain expressions and replace them with something else.
+It can be used e.g. to turn BB Code into html, so it is possible to use BB Code in the chat to format messages.
+To do this, use this Regex-Match '\[(u|b)\](.*?)\[\/\1\]' and this Regex-Replace '<$1>$2</$1>' and your text will be '[b]bold[/b]' or '[u]underlined[/u]'.
+You can also use smilies by using this Regex-Match '(?-i::(cry|eek|lol|sad|smile|surprised|wink):)' and this Regex-Replace '<img src="/pictures/$1.gif" alt=":$1:">'
+And now if you enter ':smile:' an image with the smiley will be loaded from your server at '/pictures/smile.gif'.
+The following should be escaped by putting '\' in front of it, if you are trying to match one of these characters '/ \ ^ . $ | ( ) [ ] * + ? { } ,'.
+I used '/' as delimiter, so you will have to escape that, too. The only options I used is 'i' to make the regex case insensitive.
+If you want to test your regex, before applying you can use this site and enter your Regex and Replacement there and click on preg_replace: http://www.phpliveregex.com/
