Hi @purrix, my sincere apologies, I was having a 'silver' moment, but had already curated your post for ocd so I'm sure it will get a nice upvote. I must check why some subscribers show up as a Member, it may just be the ones who chose their Silver Bloggers 'nickname'? I'm sure that's what it is.
Maybe you'd like to decide on choosing your 'Silver' name? I can add one if you like.
By the way, there is nothing wrong in posting to a community you have not joined, many Hiveans do it.
Sorry about the misunderstanding!
