If your membership information is not up to-date, mail Moonbars about it. The medal system works like this: Gold is for 1st place. Silver is for 2nd to 10th place.
bigger medals are for TOCs, TAGs, TOMs, etc.
Please report all your finishes to me so I can post your medals.. I could work it out by myself but I do sometimes have a life in-between games of EN and UC. Honest.
