I dunno, but I think it would be easier to use eidogo to show a position or
variations to play. Open a blank board, play moves or set up a position and
then press the "Save to Server" link in the lower right to obtain a weblink
to share it in a forum or chatroom.

Though the board is not as nice as the webversion of sabaki. But sadly, you can't
save an sgf there for easy sharing like you can do with eidogo.
