I just found out about this, so I just posted it here. Don´t know if you Guys already know it, but here you go: If you want your Gamerenders Forum Screen to be Bigger or Smaller, like Zooming In and Out, just Hold your "CTRL" Button and Press the "+" Button to Zoom it in. To Zoom-Out, hold the "CTRL" Button and then click "-" And it will Zoom-out and have a good look. There ya´ go, mates! I prefer it with One-Time Zoom-out...
Also, if you press "ctrl" and move the mouse whell thing in the middle (if you have it), it does the same thing
