In case anyone was wondering, I sent him a mail explaining a thing or two to him, including some minor threats (stealing html and taking credit for someone else's work is a violation of the user policy of his ISP).
Anyway, he honestly must've crapped his pants at this, he immediately retracted all his programs, credited me, redesigned the pages and put out a public apology. So there's nothing to bitch about anymore, except maybe for his ignorance, not realizing removing my name from the code was a no-no. Oh well.
