Now with more than 5!

Check out some tutorials, guys. Watch some pro matches with commentary (ie WarOwl, whisenhunt). It'll help you realize some behaviors and practices that should be used when you guys are playing in matches.

Also, do not solo queue if you guys want to get out of Silver. Stick with the team and friends that you know have good teamwork and decent enough skills. Even try avoiding maps like Dust II, Inferno, Mirage, etc. All of the popular maps, essentially. Play on less popular ones. You are bound to run into smurfs and hackers much less so, and you will certainly get out of Silver. Especially if we stick as a team.
