What Is Mere For?
Mere is the standard by which we measure the time period between now and the beginning of a LAN event. When we say the beginning, we mean the earliest time which a participant is officially allowed to arrive. For some LAN parties, this will include an Early Arrival Service. So if an ‘EAS’ is available, it is taken as the beginning of the event.
But how do we know when we are allowed to call Mere? Well, there are two widely adopted standards for levels of Mere. These are known as S.O.D.D.O.M. and Expansion. The difference between the two standards is basically the grey area concerning plural time measurements. Read the relevant links above for more information about how the two standards are calculated.
