DreamForge-Games have added a forum to their website.
From their announcement:
With the (hopefully soon) beta testing of Iron-Core it was time to open a forum.
Why a forum when I have a blog? A blog is a great place to post news but when you need feedback or a place to ask and answer more in depth questions, a forum is a far better tool. It also allows me to email all my members with important news such as pre-orders and new product information as well as special offers.
