I have recently begun mining Litecoin and am still fairly new to the crypto-currency community. My main concern at the moment is that whenever I log into my account on litecoinpool.org (the pool that I have chosen to mine in), and view my worker's stats, the only thing that shows up is the amount of invalid shares I have. All of my worker's other stats are at 0, yet my mining software is telling me that I am mining at 50Mh/s and I have accepted over 230 shares. Does this mean that I should be concerned about not receiving rewards or is it simply a delay in the site reflecting my other stats?
P.S In case it is of any importance, I have been mining for a total amount of about 8 hours.
