Regarding "Credits"

I was wondering if there is a way to see who has shared credits with me,so that in the future I know and will do the same.
Also,it might be just be being dumb,but I noticed that credits shared on different threads don't cumulate.

 

Well if u click upon your name and "wiev public profile" u can see your credits, click on credits so u can see who gave them to you..













Only bad thing is that they don't work anymore

 

Lol is all I can say
