Thanks, ughaibu.

Well, there is another tafl site on the internet that has adopted the rules used here at brainking.

It is http://aagenielsen.dk/
There are several tafl games and you must select 9x9 Tablut with "Marseille" rules. Those rules are identical to ours. However, I do not think I was able to convince them of the perpetual check rule.

And the site is only live play, no correspondence.

That makes three sites now (brainking, dragonheelslair, and aagenielsen) that has this version.
