Initially every member gets the member rank zero and it improves according to the contribution of the member. Your points can be recalculated and increased every time but member level is not possible like this. Every week, only Sunday evening it changes on a very transparent manner by computer based programs only. So, if I am not wrong then you have to wait till Sunday evening to get your rank level. That rank level will be with you for a week. That will change according to your contribution. If your contribution in that week is less as compare to other members then it may be go down. Similarly if your contribution is better than others, it will be move up and you will get a better rank then the earlier week. So, don't miss the chance you contribute more in the remain days and can get a good rank and member level in coming Sunday.
(Expect for the best but prepare for the worst)
