All sell orders will be gone in about 20 minutes.

Traumschiff, I'm mining on a Phenom II 965 running 4 instance of simpleminer. Averaging ~50h/s on the pools,it will fluctuate depending on the shares submitted. So i guess yours should be more. I'm getting an average of 0.023MRO per block, peanuts but its better than nothing.  .

Nope, staking usually finishes after 50 blocks are generated in the network.
If you double click on the transaction for mining, it should tell you the details.

Once the coin started staking, I dont think you can send it.
You will have to wait for the staking to finish before sending any coins.

Do you want to send the coins?  Stake means you are going to earn interest on that coins and you can remove it by sending the coins anytime
