Welcome back @paulinemareewilson, it's great to see you came back - what was it that brought you here this time? Remembered how awesome the community was?
We've recently had Feverbee's SPRINT London event over here, which was heavily focussed on how to use psychology to increase engagement in our communities - this thread may help with the links to the slides, but also keep your eyes peeled for the videos at some point too (hopefully!)
Please do this - it's great to hear how things play out for people that come here seeking advice. And remember to come back if you have any other questions ro just want to sound something out!
