Subscriber form

Hi Everyone.

I’m brand new at wp.org so please bear with me.

I am trying to upload a very simple plugin that puts a widget on my blog to allow readers to subscribe to posts.
I have tried several and I’m getting into a real tangle as they simply don’t work.

I have subscribed to them myself but don’t receive notifications of new posts.

I’m probably doing something really stupid. Please help.

Thanks
Chris
