You may need to change the pool address in the config files to this: stratum+tcp://xmr.poolmining.org:3032

Else, like Ben said, you're mining in a completely different pool =P

Have you checked if the miner software is actually running or not? Try restarting it to double check it...

That's for the entire MONA network. Someone on the network for those blocks, and that someone earned the reward for those blocks. The blocks this pool finds are described in here:

This isn't a Pay Per Share pool, it's a Pay Per Block, meaning you only
get awarded when the pool finds a block. If the last block was found 8 hours ago of course you still haven't received anything if you've been mining for 5 hours. Also, take a peak here: https://poolmining.org/faq

You're telling me that with a GTX 950 and a GTX 1060 3GB I've gotten more than you've made in those 12 hours? O.O

So, when will that Slack room be enabled to all of us? =P

I still don't read German, but I can pretty much guess what this is: https://poolmining.org/faq

Why is my reported hashrate zero or different from what my miner reports?

Pool and miner hashrates are re-calculated every ten minutes. Therefore it can take a maximum of ten minutes for your hashrate to update depending on the submission time of your first valid share. The hashrate we display at the pool is a rough approximation of your hashrate based on your submitted shares and can therefore differ significantly from the hashrate displayed locally. When in doubt always consider the value displayed by your miner as the correct one.

Google Translate:

Warum ist mein gemeldeter Hashwert null oder verschieden von dem, was mein Miner meldet?
Pool- und Miner-Hashraten werden alle zehn Minuten neu berechnet. Daher kann es bis zu zehn Minuten dauern, bis sich Ihre Hashrate aktualisiert hat, abhängig von der Einreichungszeit Ihrer ersten gültigen Freigabe. Die Hashrate, die wir im Pool anzeigen, ist eine ungefähre Annäherung an Ihre Hashrate basierend auf Ihren eingereichten Freigaben und kann daher erheblich von der lokal angezeigten Hashrate abweichen. Bedenken Sie im Zweifelsfall immer den Wert, der von Ihrem Bergmann als der richtige angezeigt wird.

Well, I'm not sure if I was affected or not, but just in case: MTvCM8smh9bikfczV5Dxy9p6AXQPzi6Xeb (MONA)

Well that's true the ZCash pool here has been fairly unlucky. Not a single block found yet =/

By the explanation I see, it seems that all shares are placed on a Stack, and once a block is found, it pops all the shares of the the stack until a per-determinated point. Then, those popped shares are used to calculate which percentage of the reward each miner deserves.
