I downloaded the new wallet and didn't have to do anything else which is cool. Now will it mint extra coins today or doesn't it mint daily? I haven't minted any for nearly 2 days and I got wallet open most of the day I am online also pinned it to taskbar. I have it unlocked every time I am online. Is there anything else I need to do to start minting again? Or is it just random?

I also have an idea..Why not we all contribute 1k each and do a massive mintpal voting giveaway and get more peeps to vote on mintpal and give them a treat? I could help with that as I do giveaways all the time.
About how the coins are minted, there is a discussion in the previous posts.
Simply speaking, two things you will need to do :
1. have your wallet unlocked;
2. wait for AT LEAST 24 hrs;
For the first mint, it could take 24 hr and even more.
In the thread, some guy had waited for 4 days to mint his first coins.
Be patient! Longer you wait, more coins you will get.
