Hi Jan
Newbie-friendly games start pretty regularly, keep an eye out in the multiplayer subforum. And please don't feel you need to play much more SP before you join an MP game. As long as you have th every basics go for it, you never learn as much as you do by MP games, and no matter how much SP you have under your belt you will still be surprised constantly against experienced human players. Just suck it up and dive in
1 turn per day is really not much time at all, and as games get later the hosting intervals normally go further. If you are unable to meet time for a specific turn the game admin will almost certainly postpone it for you - happens all the time, we all have our lives
