well, writing FEELGOOD is not necessary, better forget it,
you just have to litterally copy that : hive-190931
and paste it as your first tag

and that action will automatically place your post in the right community

There is no @ or # before, just hive-190931
just try this way, copy it and paste it, don't make it harder than it is already 😉

I know this is a bit confusing, because once your post is published, it will appear "Feel Good" at the place you had written "hive-190931"

...so the confusion is at its maximum, this is soooo understandable, maybe one day things will be simple, for now I can just sympathize with the new comers that have this big learning curve before them, indeed....😌
