For about 2 and a half years I have blogged on this site with a (then) modern software package. All went well, nothing wrong, but recently (about a week ago) I have upgraded this to the latest version of their program. As a result of this, the site now uses a responsive design, meaning you can see this site on your “device” meaning iPhone, iPad, Android or any other type of tablet and enjoy it with an appropriate layout. The top menu might change its appearance as well as some other elements. All depending on the device you are using to see the site.
This has taken some time to get it right and as a result, the emails going out to subscribers of the blog have gotten mixed up. It seems that you now get emails about “new” posts a few weeks old! Since this is Google’s Feedburner doing the job, I expect this to resolve itself in the next few days or weeks. There is nothing wrong with the site and it is not trying to spam you, it is just a bit mixed up in the dates, it seems.
In the mean time, enjoy the posts, even the older ones!
