Also if you're looking for more comms to join, you could try followfriday or dw_community_promo. They don't update allllll the time, but when they do there can be some pretty cool posts. copperbadge also tends to run Radio Free Mondays, where people can post things like fundraising drives (things like GoFundMes or Kickstarters or things like "how to help with this natural disaster", and also job and roommate posts). Sometimes the RFM posts are listed on signalboost. synecdochic runs a weekly-ish "thing I did this week I'm proud of" post that is pretty popular (roughly on Mondays); the spin-off comm is awesomeers. I could list other great comms but idk if you're interested?
