When I look at my week user reputation it says I'm 0.81 on it at rank #4. I don't understand the stats that I see there:
What do the different stats mean? I understand total reputation and week rank (I don't know how that's calculated) but +39 change from when? The start of the week? Today? And week reputation I believe is reputation gained since the start of the week?
And I notice now when I try to putt a tag in I must put one of the following listed. Am I writing on the correct stack exchange site to ask this?
