Okay where in the world do I find out how much sP I have?

Go to Personal > UserDashboard. It's near the bottom of "Your Stats".

What you have on-hand also displays on the Subeta: Username widget on your dashboard on the left-hand side of the screen; if you don't have that, you can add it here. Also if you've got your dashboard set to Events it won't show your widgets unless you click on it

How do I add username widget? I'm not too savy on this sort of thing.

It's the one that says Subeta:ChaosEmpress for you c: Just click Add Widget and then you can drag and drop it where you want it, on the lefthand side

Thank you very much! I almost forgot to thank you too. So thanks!
