levels of expertise¶

• interested
• pursuing
• beginner
• apprentice
• intermediate
• advanced
• accomplished
• master
• grandmaster
• great grandmaster

setting rules:¶

level	who can set + requirements
<=‘beginner’	oneself
‘apprentice’	someone else >= ‘intermediate’
‘intermediate’	someone else >= ‘advanced’
‘advanced’	someone else >= ‘master’
‘accomplished’	oneself = ‘advanced’ + someone else >= ‘master’
‘master’	one’s apprentice =‘accomplished’ + someone else >= ‘grandmaster’
‘grandmaster’	one’s apprentice >= ‘master’ + other >= ‘grandmaster’
‘great grandmaster’	similar to ‘grandmaster’

I know that without additional logic one can’t graduate to ‘master’ and ‘grandmaster’, extra logic for existing ‘master’(s) required. For example when 2 or 3 people from one level can act as one person from level above.
