Too many people are not following the guidelines - rules for issuing Formal Challenges.
Its pretty cut & dry:
Formal Challenges(added 6/28/02)
The Formal Challenge is to only be used if other attempts at trying to get a game with a particular player have failed. Players abusing the formal challenge may be penalized.
You might say, what are other attempts:
Open Lobby Challenge
E-Mail Request for a match.
As I continue to receivce Formal Challenges, I will not play them unless the challenger has followed the rules.
Invalid Formal Challenges will be forwarded to the OP's and Cases Complaint as a breach of the rules pending penalty.
