I definately can't argue with the spirit of how this was designed to play. Being able to take your time and think about stuff is cool, it's only that sometimes I want to get a quick game in and it is almost impossible unless you have some players with the same idea.
As for a premium member package thing that's not a bad idea, however it is nice not having to pay for this site. Don't get me wrong I appreciate the time and effort that went into designing this site and can appreciate it. I myself am a database / web application programmer for a law firm and know how much time goes into something like this. I would not mind making a donation or something like that but depending on how much the premium package will cost we may loose alot of members to the site.
I don't know if the goal was to make money off of this or what future ideas are in store, and don't get me wrong, you can't fault a guy for wanting to make some dollars, I just think that this is such a great idea that I would hate to see it get out of control like other games sites have. Just a thought.
