I knew jaytea would eventually come along to reward me with his viewpoint. I oblige it very much, as not all the snippets can deserve jaytea's input. I love to have something to read up on as well. :p But as I said, this snippet was merely written for fun's sake. I was trying something rather unconventional if I may say so. At least spare me with some effort in making it. ^^
So, jaytea, shed me some light on the matter of wildcards. For instance, the word hell is regarded as a bad word on the list, and I certainly don't want it triggered for "hello" without using \b.
