College Student: need help with Alarm!!

[Mastanthony89]

First off i would like to say that i like my Mogul coming from a Motorola Q. Having a smart phone to log assignments as well as meetings in college is very helpful.

One thing i cannot get to work right is the alarm.
On my Q the alarm woudl still go off even tho my phone was on silent (my roommate has a prissy fit if my phone makes noise at night time, (ie. Emails, texts, etc)

Is there anyway to set my alarm to go off in the morning (vibrate and ring i would prefer) but keep my phone on silent all night? please help me out or tell me what software i need to make this work right!!! thanks soooo much!
