For those of you wanting to use the Subscribe 2 widget but are not seeing it in the widgets options, you have to turn it on first. Yeah, stupid huh?
Go to the Subscribe2 button under Tools and scroll down until you find ‘Enable Subscribe2 Widget?’ and check the block. You can then go to the Widgets and drag it to the side bar. You may also want the SubScribe2 Counter which gives you a count of how many people are subscribed to your site.
If you want to send a message to your subscribers without posting, you can go to Posts – Mail Subscribers. This allows you to send an e-mail to your list.
If you need to see or edit your subscriptions, click on Tools – Subscribers. That will show you who they are and allow you to add or delete.
I think you will find Subscribe 2 a very useful communication tool.
