Each member has a 'star' rating. The site coordinators who take into consideration the contribution made by the member in his/her posts determines the rating. This assessment is usually, but not always, carried out following the submission of 20-30 posts, but the actual number made is not influential in the decision making process with regard to upgrading.
The posts must be considered to be of value and/or assistance to other members – simple one-liners and ad-hoc comments, although included in the post count, are normally disregarded for this purpose. Members may also be ‘downgraded’.
