silencing some notifications ??

I am making baby steps with my new Droid 2.

I have always , with any phone, been able to silence my notifications. ( texts, emails etc..) and still have the phone ring. I do not like being woken up by notifications in the middle of the nite, but need the phone for emergencies. ( unfortunately have had to many of those 3am calls )

I went into settings, notification ringtone, and there is no option for "none" or silent..I really need the phone ringer on, and everything else silenced... hmm I'm stumped..
thanks in advance.

yes i would like to do this as well!
can u use ringtones for text messages that u download? it only lets me use the one that were installed
