The correct sites are slicer.org and [slicer.readthedocs.io](https://slicer.readthedocs.io/en/latest/user_guide/modules/extractskeleton.html).

Any reason the organization doesn’t own both [slicer.org](http://slicer.org) and [3dslicer.org](http://3dslicer.org)? Looks like [Slicer.org](http://Slicer.org) was created in 1999 and [3dslicer.org](http://3dslicer.org) was created just recently on 2021-11-09. Info obtained from [ICANN Lookup](https://lookup.icann.org/lookup).

Good luck with [3dslicer.org](http://3dslicer.org). It’s parked by Transure Enterprise Ltd. They’ve got complaints against them ranging from Bank of America to BHP Billiton.
