For the past 10 years, I have run the forum for investors in solar, and with the switch of my interests to biotech recently, I decided to open an investor forum for this purpose. The new site https://biotechinvestor.info/ is a free platform, which I hope to consolidate info on biotech investing ideas from all walks of life investors in the sector. There is a lot of information with comments made on SA articles but they are scattered across this vast site. Yahoo forums are not the quality they have been, a reason I started a solar site about 7 years ago.
If you are interested, joining is easy.
