@tarazkp there is something I don't understand about the sp. My account showed something like 3sp (+13) (am just using this number as an example, not the actual figure).
So when I started having bandwidth issues I decided to power up with all my earnings but instead of the sp increasing I notice that each time I power up the sp just add to the number outside the bracket while the number in the bracket reduces to give me just about equivalent sp as what I had before.
Right now I have power up about three times but the value in the bracket has totally vanished. Please how do you explain this?
