So, I'm in a bit of a fix. I have to be at a camp where I'll be using the institute's computers. They don't have Java.

Is there any other online website where I can teach others Go like I can using the KGS interface? I just want something that allows creating new branches of moves. Notes, numbering and marks are an added bonus but are not necessary.

Any help will be appreciated. Thanks

Based on how quickly it loads I would guess that eidogo doesn't use Java. I can't find any conformation of this though.

Kaya's Sandbox feature might suit your needs. I'm imagining that you want to load up sgfs and play out variations.

1) Is there a way for someone to see live what changes I'm making on the board in EidoGo? That's basically what I wanted.
2) From what it looks like, I think Kaya's sandbox has an option for spectators. I'll have to try it to be sure, though.

I'm not sure I understand the question. Select blank board and start clicking.

Will someone on the other end of the world be able to see my clicks while I am doing them?

Sorry, I completely misunderstood. I thought you wanted to use the computer to teach the people at the camp.

With Kaya's Sandbox yes, though I don't think you can load SGFs into it yet. Or at least when I load a sgf on there and then try and open it in a Sandbox I get an error. I assumed since you said camp that you were going to be using a projector or something to display for a class. This was confusing me as you could use any of the desktop sgf editors for this purpose.
