You prefix everything with classic.  For example, the main page is classic.theeroticreview.com.  The discussion page is http://classic.theeroticreview.com/discussion_boards/index.asp and so on.  The link on these two links I posted here have links to all the TER pages.  It is not just the discussion page.

For those who know...how do I temporarily switch to classic version of TER?

Google TER classic version and it comes up
as one of your choices.

I did.  It only shows discussion board discussion on it, not the actual ter classic version.

Oh cool.  That's very helpful.  Thanks.
Thanks all for replying with help.
