wiki New useful function

[Lord Henry]

Hello everyone.
I created a page with an useful function. But I think that it's too hard to others understand. So I need an experienced user or moderator to fix the page or tell me what to do.

FadeInText

You could name the function "fadeText" and use a boolean for fade-in or fade-out.
Also you should maybe use local variables, cause right now there is the risk that this code could break some other clientside codes, if the user used too many global variables, too.
I don't like the performance of the script, but I think it won't get used that often.
