Cube Tutor is closing down on November 1 at 10:00 am BST, and all lists will be irretrievable once that happens. Make sure to either download your list, or export it to a Cube Tutor alternative such as Cube Cobra before that date.
RIP Cube Tutor. Ben's right that the site has left a legacy and you can clearly see it's influence in Cube Cobra.
I personally stopped updating my CT list about a year ago and moved to CC but it's still been a pillar of the cube community since its inception. I was always a bit envious of the old-timers getting around with 3-digit cube ID's.
Ct had a great start. Unfortunately ben got lost in rhe process to make it an app and burned too many ressources there. Once he noticed his on a track to nowhere the main page was already falling apart.
