Just opened Scottrade account, how do I deposit?

[vindikation]

I just opened my Scottrade account this Saturday morning. I can't call them on weekends and want to know how I deposit money into my account. I have an eCheck form that asks me to attach a voided check and mail it to them. After they receive this voided check, will this allow me to deposit money electronically or mail them a first check to open my account?

Thanks

Oh yeah, I'm almost ready to create my "What a complete noob investor has learned after 1 month of research" post.
