If you backed Mighty No. 9, you should be getting an email soon with your login information for the new website, which has officially launched. Right now there isn't a whole lot you can actually do on it, but news updates will be steadily flowing through it over the coming weeks, "straight from the developers," which is great news.
The forums right now are for backers only, but that may change in the future. Now, all we have to do is wait. It will be painful. Hold me.
