Snuzzer, if you create scripts that are based on other's work, please make sure you mention it in your script (and not only there) and include a link to the original script.
Also, read what it says at the top of some scripts, usually the authors include some sort of license agreement and you should comply with what it says.
If it says don't copy this script, then don't copy it; If it says ask for permission, then ask. If you're not sure if you're allowed to mess with a script, ask the author first.
