because to be a member you should get at least 60 posts and 10 merits
Small correction; Activity, rather than posts is the requirement. Op presently has made about 80 posts but are not yet ranked up to member as they have to reach the required activity.
Note: Activity doesn't follow post number strictly. Activity points are counted biweekly, so you get 14 points if you make at least 14 posts within a 2 week period. You only need to make at least one post a day to rank up at maximum speed.
You also need at least one post within each activity period to be parsed. If op were to stop posting now, their activity would never meet up with their post count as they would not qualify for any other activity window (except the current one).
