To be honest I unsubscribe from all the leagues I have loaded, but am not currently playing in. These helps keep my inbox clutter free. I also download tactics, this saves me time from analyzing every pre-match, adjusting tactics, instructions, etc. Yes, this does take the some of the "manage" out of Football Manager, but it does save a lot of time. Also if I'm comfortably leading in a match I'll speed up the highlights or even switch to "commentary only." If I have a week or more between matches then I'll holiday to the day before the match. Be careful with this though because your assistant manager can do screwy things with your training.
