    Which video tutorials will allow me to create such? a system?

  18. EpicATrain says:

    Because of this video alone (not using part 2 or 3 of the regex videos because they use python), I feel as if I became a regex master. I wrote an elite language filter for minecraft using the information from this video. Check it out:

    Feel free to use them as examples in your tutorials. :) My next? goal is to create an interactive website that can create an custom language filter for each server admin, based on what check marks they make.
