I know how to log into more than one account at the same time for Windows, but I tried the same method for Mac and it didn't work. The CGoban3 log in window just doesn't appear after I close it. Anybody knows how to do it for Mac?

Use the online applet? Run multiple copies of CGoban from the command line with "java -jar path/to/cgoban.jar"

Make a copy of cgoban.jnlp first.

Thanks for showing me how to do this on Windows. I don't know why I'd want to, but it's nice to know, I guess.

I tried that method and they say unable to access jar file. Using the online applet works though.

That method worked!!! I downloaded a new copy of cgoban.jnlp, and open that one everytime instead of the cgoban3 app they created, and I can log into more than one account without any problem!
