As you say I don't think the community is quite large enough to warrant a separate board, yet. It's possible once we expand to Steam and get even more players.
That said, we
do have a number of French-speaking Cogmind players here, most of whom are from
Roguelike.FR and hang out over on
their forums. Being a French roguelike player you've perhaps already heard of them? In fact, on checking out their site again I just noticed they posted about Cogmind recently--they've been doing some LPs--no wonder there was a surge of interest recent (and more purchases than usual). I couldn't tell where it was coming from
(I've moved this thread into the General board, since it's not Cogmind specific. Also, we have a
Forum Feedback thread if you have any similar suggestions. Thanks!)
