The Forum is an awesome new addition for the community to have conversations but I dont think it can replace ideas.storj.io at the moment. Part of the reason we use the ideas portal is because its a part of Aha which is the product management software we use. If you submit an idea I am able to convert it into a feature and get it slated into our roadmap and then you can track it! We can integrate the ideas portal into the forum to make it easier for you all to submit your awesome ideas!
