I have had a few people say they have subscribed to my newsletter but cannot find the extra entries code in it any where. I thought I would show you the example of the newsletter and another of the Rss feed because I think that is where there may be the problem.
In the image above you can see the Top of my Rss Feed, if you get a DAILY email that looks like this with the PLEASE NOTE then that is the RSS Feed and there is NO CODE there. The newsletter comes out every Friday ONLY and there is a code at the bottom in a section that looks like that in the image. There is only a code every OTHER week.
Hope this helps!
