Hello, sorry for posting at this place: what does it mean, if some persons avatar is been displayed with a “halo“ or blue gloriole?
I seem to not be able to figure it out…
I believe it means they were the last person to post in the thread (if they were also the OP).
It signifies that the most recent poster is also the original poster.
Blessed are those who reply to their own posts: for they shall have the last word.
Except when they don’t! 
“Their postings are buried in peace,
But their names liveth forevermore.” 
Thank you 
I am blessed with knowledge now
