To subscribe to any wordpress blog, one does have to type in their email address and then click on the Subscribe button.

A message is then logged in the blog owner/blogmaster that someone is subscribing to their wordpress blog.

Every time I post a new article and it gets published, every subscriber automatically gets an email alert and alink to new article..if they are interested.

Hope you keep on writing for your blog. When one has time, it's lots of fun. Right now, just going a little nuts. I'm working on a 4th blog which will be released publicly late next month.
