Op Posting 101

Currently, we are fighting at 200 Million Pr. This means that to receive op, its Pr must be AT or BELOW 50 Million.
This is because to recieve op, it has to be under a quarter of the total of your Pr.
For example, Player A wants to post for Player B. If player B is at 200 Million, then Player A has to post 50 Million, because one quarter of 200m is 50m.

Ideally, though, you will want to fight a little bit higher than 200m, say 220-230m. This is because if you are attacked twice in quick succession at 200m, the op may not reach you the second hit and you could lose planets, such as being hit and falling below 200m - which would cause you not to recieve any op.

Also, our current fed rules say that each race should post these ships:

Terrans post Cancer and Gemini
Marauders post Large Strafez Fodder and D.Dominions
A.Miners post Cancer and Gemini
Guardians post K.Hun-Li and K.Hun.Xe
Collectives post Cancer and Gemini
Viral 105s post Large Strafez Fodder and D.Dominions
