Hello!
How I can see the list of commands for immortals? wizhelp does not exist.

Just use commands I think. It breaks them down into levels.

thanks! another question:
How do I delete an area?

No way to do it online. You have to go in and manually edit the area list and hotboot so it isn't installed. That is a good idea though might make a flag so you can have it remove an area from the area list so it doesn't reload it next startup. Would still of course have to manually delete the area file.
