Hi Jin-oh,
Hmm.. what to say.
1. SqueakMap is old and most people use http://www.squeaksource.com with Monticello.
2. It's an orphan because the person who built it has gone to Pharo.
3. Having said that, try this http://76.74.255.163:8080
It's a replacement for the SqueakMap server I've had on the back burner. Give it a try. I'm pretty sure it'll crash, but you could help by telling me what happens when you use it.
That's all I can suggest, Chris
