I know this wasn't addressed to me, but I'll like to say that some people make it more difficult than it is. If you have an odd work schedule then, try to find a small league or a create a "Day Time" league or something like that.
Like I said, my first league was with two of my buddies from work in NCAA 11 and the three of us have been playing together ever since. We all work together so our schedules fit, however we have other real life things that get in the way too. While I don't have any kids, one of the guys has two and the other has one and another on the way. Sometimes each of us may have to work out of town or are on vacation or whatever, so we don't even have a set advance time - we just wait on one another.
In my OS OD's that typically has 12 guys we have a 'hard' three day advance rules. Most of the times guys can get together and play within the time-frame ,but sometimes they may have conflicting schedules and games get simmed. That's just the way it is and it's understood. I'm actually going to be in two 32 user Madden CC's this year. One is going to run along side the NFL season, so only one game a week which should be a piece of cake. The other has two advances a week and I'm anxious to see how it all plays out, but I'm fairly confident in most of the users due to knowing pretty well from on here.
Anyway the moral of the story is if you can't find a perfect league for you, then create one that suites your needs. You may be surprised at others who are in the same situation as you.
