They wrote cola because the site is frowned upon being used here. If you try to give the real link (which starts with a v instead of a c) then the link is obscured (as a spam link), or sometimes your post is refused altogether. Plus you receive a "strike" and informed continued linking like this can result in a ban here.
Anyway, I checked out the room. There's a couple of pretty good posts. So thanks for the link >>76570
