All the stuff about permissions. Kris, get lets you pick things up again. I had to look at boostrap.txt to find that.
Error messages are terrible.
The new POO supposedly fixes many of them, but I couldn't figure out the new syntax. The Telnet support on Working Man's MOO doesn't support pasting code in that you've saved elsewhere, but UNIX does, and if you telnet through UNIX, you can paste code in that you've edited in BBEdit or something else. Don't do this too much or performance will suffer. The POO does crash occasionally. So far, everyone is a wizard.
