If you are using the latest versions this feature does exist. To use it find
a position you would like (Cube or Move) and then on the "edit" menu select
"copy as>"/"GammonOnline(HTML).

This will put HTML in the copy and paste buffer that can be pasted into an
html file to show a pretty graphical board of the position.

The documentation for how GnuBG ID (Match and Position ID's) can be found
here:

http://www.gnu.org/manual/gnubg/html_node/A-technical-description-of-the-Mat
ch-ID.html

The key thing to note is that the Matchid and PositionID are base64 encoded.

If you are using newer version of GnuBG you can copy all 4 lines above into
the GnuBgID text box (In the GUI) and GnuBG will actually strip off all the
extra stuff and convert and combine it for you.

Hope that helps.
