uc_recurring module

Hi All,

I am working on the uc_recurring module. I have few questions.

1- How can I test recurring payment in same day if interval time is 1 day?
2- How can I send custom notification emails to buyer and merchant. I am using only paypal_wps paymeny gateway using paypal?
3- How can both (Buyer & merchant) cancel their subscription using my website.
4- If payment is failed then then how can merchant contact with that buyer.

I am using Drupal 7.x version and uc_recurring module version is 7.x-2.0-alpha3 with ubercart 7.x-3.3.

Please help me.

Thanks
Rishabh
