Love it, using it.
However... a question... your screenshot kinda shows that $vboptions aren't getting through to the end page. If the password was wrong or something daft like that, you wouldn't have $vboptions.
It's probably best to advise people to hardcode their forum info and email into that error page and not rely on something that you might not have... in fact probably won't have... it is an error page afterall
Oh, and I remove $message from mine after accidentally leaking my database password to the web!
