I apologize for an agonizingly newbie question, but after not playing for several months I'm going through the tutorial after the 2.0 drop to get accustomed to things again. And I come across a Capsule which gives me credits and Experience Points +5. For the life of me I can't remember what "Experience Points" do for me. I looked in the PDF manual and searched the Wiki but no joy, probably because it is obvious. Any help would be appreciated, thanks!
