I couldn't remember the "menu" and I also think there is a difference in the amount based on what section of the Forum you are posting in, but I'm not sure about that?
Could be. I have not made an attempt to find out everything about this, I've just noticed a thing or two. Like this post will give me an additional 5 credits. And it also gave threadstarter Marto 1 extra credit. Which shows you don't get "double credit" for being a mod, only for being a premium member.
I will post further discoveries here if I make any.
This is to see if I get more for editing a post.....and I do. The 1st edit gave me an additional 2 points (your seven is 5 for the post and 2 for the edit) the 2nd edit gave me an extra 0,96, the 3rd an extra 0,14....and the 4th an extra 2 again! I really don't see why. I suppose it has something to do with time spent, as the 2nd was short and the 3rd very short indeed, yes, the 5th edit also gave me 2 credits after I spent some time on it. Could be length or writing as well as time spent, will check that now....yes, definitely length of writing. Took as long, wrote little, got 0,04 credits. Interesting!
