Rewrite URL's going to sites.webec.com.hk (Meffert's site), to add the "?refer=TwistyPuzzles" to the URL (unless the "?" is already there, then "&refer=TwistyPuzzles", so people posting a direct link will still give this site referral credit.

If your using firefox, make a bookmark to "http://twistypuzzles.com/cgi-bin/link.cgi?link=47", and add the keyword "mefferts"
