I came up with this because you and someone else asked about it:

It doesn't hide all text but I think it handles the quoting issue (assuming the quote has the username in the tag).
Edit: oh...I guess that probably won't work with vb3 the way it is, sorry about that. I can try to make the changes for vb3 if you're interested.
