Only staff can create new threads in the ISO Cellar, and your post is (unfortunately) a very immediate example why - you haven't checked that LSL 2 through 6 and LSL VGA are still sold (and if it's still sold, we DON'T muck with it).
To be allowed in the ISO Cellar, a game has to either a) be on the site under "Abandonware" or "Freeware" status or b) have been approved in the
Requests Forum.
In order to add a game to the Cellar, you have to post the liks to the CD images in
this thread - someone from the staff will check the game's status and either add the game to the Cellar (if it's allowed) or remove the links and drop a mallet on your head (if it's not allowed).
