I am a newer user (this is my third season) so here are some random thoughts
I think that you make some great points here. I know that when I first started playing, I didn't really use the forums at all, because it was so difficult to find anything there. I also like the part you wrote about the simple advice you got from Jbmrock, as that's the general sort of advice that I have tried to give out myself (whenever anyone has asked me).
One thing that really helped me, as a new manager, is that I started out with a team full of very good defensive players (my five best overall players pretty much all had respectable defense). This caused my team to win almost every game, which was fun, so even though I didn't really do anything to improve my team (for my first whole season or so), I still had fun watching my team play. This kept me interested in the game near the beginning, and eventually, I starting learning more about how to manage my team, and really have had a great time playing Buzzer Beater.
A couple season ago, when I was still somewhat of a new player, I thought about the things that had made my team good right away. I wrote a guide about this, and shared the main points with several brand new players that I have mentored. However, I never really saw a good place to post a guide like this at the time, and just shared it with individual players that were interested.
Would anyone like me to post up a revised version of this guide, aimed at a player whose account was just activated? And if so, where would be the best place to post it? It might be helpful in building the user base, but I don't know. Any thoughts would be appreciated. :)
