Hi Rime, I’m not aware of any designated online space for independent alignment researchers either. Peer support networks are a central part of the plan for Catalyze so hopefully we’ll be able to help you out with that soon! I just created a channel on the AI Alignment slack called ‘independent-research’ for now (as Roman suggested).
As for the fiscal sponsorship, it should not place any constraints on the independence of the research. The benefits would be that fundraising can be easier, you can get administrative support, tax-exempt status, and increased credibility because you are affiliated with an organization (which probably sounds better than being independent, especially outside of EA circles).
I currently don’t see risks there that would restrict independent researchers’ independence.
That’s very kind of you, thanksmuch.
