e-newsletter Plugin Capabilities

Hey there,

I have been testing out the e-Newsletter plugin and I have the following remaining questions about it's capabilities:
1. Is there a way to schedule newsletters to go out to a group on time delay so that it acts as "drip" email, like with the automessage plugin?
2. Is there a way to collect additional information in the subscriber form such as phone numbers.
3. Is there a way to notify the admin of a site when a visitor subscribes?
