Correspondence chess - - watching games of others

Is it allowed to invite a friend to WATCH -- not interfere with a correspondence game?

What do you mean, interfere? And correspondence game links are public on your profile.

thanks - I meant the 3rd party could see what is going on but NOT bring in commentary.... as interference

@DrRickinCT when the game is ongoing, only you and your opponent can chat. Spectators cannot see player's chat, and they have their own chat for the game, so they can't interfere.

Ok thank you.... CSKA - but it is ok for a spectator to "watch" or spectate during the game..... right?

It is ok, and perfectly alright, at the conditions that the spectator won't DM you with clues for the game.

got it thanks.

In ICCF:
'Other participants can see the games only when they are finished, and at least 10 games are finished in the event.
The public can see the games only when they are finished, and at least 10 games are finished in the event.'
