The .impact Slack is a venue for discussing EA projects with other EAs, and can also serve as a general EA chat venue. It can be useful for getting quick answers to questions, learning what others are working on, finding people to collaborate with, and general EA networking/community building. There is also a full list of EA discussion venues on the EA Wiki.
Another relevant Slack venue is the LessWrong Slack. This has a partly overlapping crowd, and is good for general chat not limited to EA topics.
Join the slack via the form below (it can take a while to load).
