The original scripts are the result of the work of a single member, however. For example, I made an alternate Flashy Deaths effect based on Wanderer's, but most of the credit goes to him.
Everyone is free to edit the scripts(as long as they don't break compatibility or make them useless) but I kind of believe that the original creators should be mentioned.
This is also important when attempting to contact the script's creator. When I wanted a Flashy Death effect I knew I had to PM Wanderer, but what about the other scripts? I can't get in touch with the creators. Furthermore, contacting the people who wikified the scripts may not be enough because they might have copied and pasted the script without checking its contents and/or having any scripting skills.
