Thank you for bringing up this issue. The initial idea of the statuses was to make them based on your forums activity for the month, so they are reset at the beginning of each month. That's why some of you now have lower statuses that they did 3 days ago.
We have noticed that this is not the perfect scheme for measuring activity, and we do consider changing it. Most probably soon we'll make them based on your overall activity instead of resetting the results at the beginning of each month. Other ideas and suggestions will be appreciated.
