luen – you right about formalising this.
as for volunteers. i believe that we could award points for volunteering. eg. each category will have a volunteer. so we award points and accumulate them for the full year. we can also then determine the points currency etc.
event procedures: we have some available. perhaps not all is written. we just need to document them. event roles: i’ve done this one already. Feel free to improve on this.
as for promotion criteria. i guess we can put some very general guidelines. getting statistics on numbers of incidents etc is a bit difficult unless we have somebody dedicated to take note of incidents. but we can use the points scoring and attendance as data to support our proposal. however, this may need to be a small panel decision of (say) 3 senior people. somebody may need to propose and support the justification for promotion.
