What´s strange is that even though D6.15/6 do work under a single license, there are still 2 folders named RAY and ORCA which contain that: ray stuff and orca stuff.
I think that goes against any webmaster´s intention to hide the script behing his/her site or client´s site. Everytime you access the forum a big ORCA FORUM SCRIPT comes up as the title of the site... Something to be fixed, I guess.
