Anyone used the simple subscription module ?

module specific issue for modules that aren't widely used are better served in the issue queue of the module in question.

Based on the project page:

This module integrates with the core trigger system and the default email action, so you can send the form contents by email.

I don't see any mention of a feature of administrator notification.

If you want a more feature rich newsletter system, you may need to employ a different module as mentioned on the project page of the module in question.

This module adds token "Simple subscription" (/admin/help/token), TRIGGER: A USER SUBSCRIBED AN E-MAIL ADDRESS USING THE SIMPLE_SUBSCRIPTION BLOCK (/admin/structure/trigger/user) to the database and a block (/admin/structure/block).
In order to connect the dots:
- go to the Actions admin page (/admin/config/system/actions) and scroll down to the CREATE AN ADVANCED ACTION section. Select the "Send e-mail..." option from the select list and hit Create. In the following screen choose a label for this action (something like "Send e-mail for a new subscriber"), Recipient (e-mail address that should be notified of a new subscriber), Subject (of that notification email) and Message (in which you can use the "Simple subscription" token - you can reach it through the link "Browse available tokens." down the page).
- the trigger is configured at /admin/structure/trigger/user: assign the created action to this trigger.
- set appearance of the block and place it where wanted.

Hii,
I need to make a form for subscription.
Can any one tell me if i can add some extra fields to this module?
if yes, then how???

I've used this module on a number of projects and love it.  It's just as it says, nice and simple.

You set up your own sending mechanism, but the list is collected, and available for whatever.
