Share something you've learned about the ROM with a new user.
I have always had about 4 homescreens that contained a lot of widgets and some of them got elborate. It was never a problem with non GB ROM's, but discovered it was an issue with GB. I went from 4 home screens to 3 and virtually no widgets...and using the packaged launcher, MMS apks & stock kernel. I have to say this is the best my MIUI has ever ran...even on FROYO versions...
So if your MIUI is laggy, look at your homescreen setup and try to scale down on the widgets and setup.
Hold down menu and press volume down buttons to take a screen shot.
One of my favorites: hold down the home button on the lock screen to turn on the "flashlight"
Long pressing a app and swiping through screens to drop it where you want.
