I think most of the confusion is because of the combination of tribes and communities. I could be wrong here, but I think tags and hive# tags can still be used to post to multiple tribes and communities respectively. If you post from weedcash.network it will automatically post it to the weedcash community. If you want it to show in multiple communities, you could add more hive # tags. If you want it to post to multiple tribes, you still just use the regular tags. I haven't tried posting to multiple communities with multiple hive# tags yet, so I could be mistaken if someone wants to correct me on that part.
