Postboard will be getting some updates soon. The Board-Integration phase will start to take effect. Companies and Groups will be able to create a board and host a mini version of Postboard on their site as a way to offload this forum type service from their own servers. If the group has their own login already, there will be a button on their Postboard page to sign up using company credentials. This is a way to Gain alot of users very quickly.
