Is this a bug ? This user has more than enough merits and activity to be a legendary member but his current rank is still hero member.
https://bitcointalk.org/index.php?action=profile;u=558519That user I linked above was just one of them I think there's more of them who have 1000 merits and 770+ activity who aren't legendary.
:
Legendary: random in the range 775-1030
This user has only 868 activity. He can become a Legendary in the next period or maybe only at the 1022 activity mark. He got 1000 merits by default because theymos thought it was not fair to only give 500 merits to Hero Members who were in the 775-1030 range and could become Legendary at any time.
