The mental health EA cause space should explore more experimental, scalable interventions, such as promoting anti-inflammatory diets at school/college cafeterias to reduce depression in young people, or using lighting design to reduce seasonal depression. What I've seen of this cause area so far seems focused on psychotherapy in low-income countries. I feel like we're missing some more out-of-the-box interventions here. Does anyone know of any relevant work along these lines? 

Since you referenced my post, I thought I'd chime in! This was my first ever EA post. I had written a slightly modified version as a guest post for the Fish Welfare Initiative's blog, and then Haven (ED at FWI) encouraged me to post it on the forum for it to find a more relevant audience. There's a good chance that without this themed event signaling to me that my internship experience could be relevant and useful for others to read, I would never have posted on the EA Forum. Even after posting, I was surprised by the positive reception my post got, which has made me much more likely to write future forum posts -- I've already started drafting some ideas. In short, I really liked this event, because it gave me justification to post something that feels more anecdotal/personal than what I usually see on the forum. 

Great point, thank you for adding this. I still think the advice is somewhat relevant if people can find impactful non-profits working in their home countries, but I was definitely writing this from the privileged perspective of someone who can easily access university funding.
