While searching for new plugins for my blog accross this incredibly useful addon designed by Richard Miller http://wordpress.org/extend/plugins/...seth-godin-do/.

I know, its title is pretty original, but it makes much more sense when we see the quotation from which its develloper was inspired from:

Basically, it allows you to show new visitors on your site a message inviting them to suscribe to your blog, thus
1) you don't need do to it manually
2) you don't annoy your loyal readers with such messages since after 5 visits from the same IP address, the message disappears!

By default, new visitors to your blog will see a small box above each post containing the words "If youíre new here, you may want to subscribe to my RSS feed. Thanks for visiting!" After 5 visits the message disappears. You can customize this message, its lifespan, and its location. The message can be excluded from Pages if desired.
You can also set a message only for returning visitors.

You may download it directly from here:
