I understand that one must be a full member in order to upload an avatar. I would like to inquire on how may posts (or what requirement required) to enable my full member status here so I may begin to achieve that accomplishment.
Welcome back, posts doesn't count towards achieving a full member status, back in the days it was just activity but after the merit system was implemented on January 24th 2018 you now require 100 earned merit and 120 activity to rank up to Full member to have the privilege to upload avatar.
