so my miner found a block, im wondering how much of that block i actually recieved since i found it. im part of a pool any help please

i noticed that some mining pools have your worker listed with a DIFF #. i was wondering if anyone could claify exzactly what that means

whats going on everyone ive been in btc n ltc world for about 2 months now i finally signed up for the forums to figure out whats going. i noticed some other users were having the same problems as i was on notr oll.in. its not reading my hash rate or showing that im actually mining into account balance. i just want to know if anyone out there has any idea whats going on with notroll.in? this all happeneded yesterday around 8 pm eastern time when i noticed they had lost all their workers n users. any ideas or thoughts would be appriciated thank you
