It's terribly good fun though... are you playing on alt.org? The Nethack channel on Freenode is quite friendly, and people will watch your game and give advice (if you want it).
No, I'm playing on my own machine. It seemed easier (in particular that way I can still play at home when my network connection goes down). I've arranged to record all my games much like alt.org, though.
Can you dig down when you're on a fountain? Does it not do something bad? I find most things do something bad :-D
