Talking before finals?

I couldn't find any, but here is what I recommend:
No talking to other finalists.

I'd like to second that and would favour an addition to the tournament rules.

Please do elaborate!

Of course people will talk to one another so I think it would be quite silly to forbid them.

If the tournament is very small (so you know or can make a good guess who are in the finsls) and you've finished the last turn but there is still a table or two going on.

During this time you already might be able to talk with the needed persons placing the possible finalists who, say, timeout less options.
