Ideas Dumpster

I need suggestions so i have plan to start a business starting with a newsletter. At first i will be sharing diff ideas on weekly basis with people through newsletter than thoroughly build a community. It will be a dumpster of ideas where we discuss, re evaluate their ideas if needed. The intention is to help each other. Help entrepreneurs get started , adjust the risk profile and much more.

I needed all your advice how can we make it more better and if indie hackers wants to get involve with me in building this.

Thanks
