Cool
If you post the example at wiki, would be easily accessible by everyone.

While I have an account on the Wiki, I don't seem to be able to add pages to it.

I think would be nice if you add a complete example of usage as well

edit: Also you need to add it in a category.

well, this function is still to be optimized

(write the checks on your own, without using the WordFind stuff, they add a lot of overhead by unused functionality)

maybe i'll do that some time
