Important question: These sub-forums, can they be seen by outsiders? There are two ways for them to function, - either a couple of people is approved to see them, or another couple of people (the other side) is just dis-invited.
It should be the last, because otherwise no one from outside will be able to read in them, and that would be a shame, as I would be genuinely curious about how each team forges its strategies, so you can see in advance if one side looked through the other etc. . That is just politics gold.
