Not to shit on the effort you're putting in banana2995, but a forum unless planned very well and designed very well, would not be as useful as using what already exists. Like this thread, though it is very active so that's not a problem. But we also have the NautilusCoin subreddit and now a Facebook page. Reddit could be more useful, I mean if anything they should make someone as active and as eager as you a moderator on it.
If a dedicated forum is created, it runs the risk of becoming very inactive and that can be pretty damaging to the image of a coin. Instead we should focus on making what we already have as active as possible.
