Hi there! :)
Since I post everyday in Hive will not make a post in response to your great initiative.
I will leave to your consideration what I'm doing in Hive right now and last months.
Due the covid19 pandemic I have run for 40 days a challenge #travelathome with more than 100 people participating (some of them still in action).
Now I'm running another challenge #a-zmusic, this new challenge did not get 100 participants but there are a few, running and sharing good music.
In both challenge I try to support all of them and make engagement but main intention is have fun and have people active and having fun on Hive.
More challanges comming in my mind! ;)
Cheers!
