oceandavid,
Thank you for your inquiry.
We have a ranking system in place for a variety of reasons, but mainly because it encourages new members to provide insightful information within the rules and guidelines we have in place.
To attain a 'treasurer' rating is fairly simple and takes only a handful of good posts to achieve.
