How to add node as i am totally new to wallet mining.
Glad we got you synced, unfortunately in wallet mining isn't working seemingly due to the large amount of hash pointed at the network. So no worries, you are on the same page as us :-)
We are working on it, and are hoping to have it resolved by today.
We planned on potential for this sort of high volume mining at first since the blocks are low hanging fruit atm. That's a large reason why we chose to set such a high pre-mine to help insulate the inevitable flood of coins to a single very powerful miner. We don't have access to that kind of juice on our own currently :-/
To add a node you would type 'addnode=XXXXX' with the X's as the IP address, but that's a moot point at the moment, if you are synced you be connected.
Type in getpeerinfo into your console and that will display a list of whom you are currently connected to.
Cheers!
